Issue with Deleting rows from my second Table in my page

I have a Reports page with 2 tables, one show items in stock the other shows Items sold. I made a delete option for them which provides a button at the right end side of the table to delete rows out of my table. The Issue that I am having is that the Code works perfectly for the 1st table but for the second table, the code will execute but the data does not get deleted from the DB.

I think what is happening is that due to me using the same Code to delete from both tables, that only 1 works. ( I think I am not sure) After looking at it for a while trying to find potential errors I made and trying to see what else might be the issue, I decided to ask u for help!

Here the code:

<?php


$config['conn'] = array(
'host' => 'localhost',
'username' => 'root',
'password' => '',
'dbname' => 'inventarisdb'
);

$conn = new PDO('mysql:host=' . $config['conn']['host'] . ';dbname=' . $config['conn']['dbname'], $config['conn']['username'], $config['conn']['password']);


$action = isset($_GET['action']) ? $_GET['action']: "";

if($action=='delete'){ //if the user clicked ok, run our delete query
    try {

        $query = "DELETE FROM BCD WHERE id = ?";
        $stmt = $conn->prepare($query);
        $stmt->bindParam(1, $_GET['id']);

        $result = $stmt->execute();
        echo "<div>Record was deleted.</div>";

    }catch(PDOException $exception){ //to handle error
        echo "Error: " . $exception->getMessage();
    }

}

//select all data
$query = "SELECT ID, Categorie, SerieNummer, MacAdress, ProductCode, Prijs, RekNummer, PaletNummer, Hoeveelheid, Aantekeningen FROM BCD";
$stmt = $conn->prepare( $query );
$stmt->execute();

//this is how to get number of rows returned
$num = $stmt->rowCount();



if($num>0){ //check if more than 0 record found

    echo "<table border='1'>";//start table

        //creating our table heading
        echo "<tr>";
            echo "<th>Categorie</th>";
            echo "<th>SerieNummer</th>";
            echo "<th>MacAdress</th>";
            echo "<th>ProductCode</th>";
            echo "<th>Prijs</th>";
            echo "<th>RekNummer</th>";
            echo "<th>PaletNummer</th>";
            echo "<th>Hoeveelheid</th>";
            echo "<th>Aantekeningen</th>";
        echo "</tr>";

        //retrieve our table contents
        //fetch() is faster than fetchAll()
        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
            //extract row
            //this will make $row['firstname'] to
            //just $firstname only
            extract($row);

            //creating new table row per record
            echo "<tr>";
                echo "<td>{$Categorie}</td>";
                echo "<td>{$SerieNummer}</td>";

                    echo "<a href='#' onclick='delete_user( {$ID} );'>Delete</a>";
                echo "</td>";
            echo "</tr>";
        }

    echo "</table>";//end table

}else{ //if no records found
    echo "No records found.";
}

?>

<script type='text/javascript'>

    function delete_user( id ){
        var answer = confirm('Are you sure?');
        if ( answer ){ //if user clicked ok
            //redirect to url with action as delete and id to the record to be deleted
            window.location = 'Remove.php?action=delete&id=' + id;
        }
    }

                    echo "<a href='#' onclick='delete_user( {$ID2} );'>Delete</a>";
                echo "</td>";
            echo "</tr>";
        }

    echo "</table>";//end table

}else{ //if no records found
    echo "No records found.";
}

?>

<script type='text/javascript'>

    function delete_user( id ){
        var answer = confirm('Are you sure?');
        if ( answer ){ //if user clicked ok
            //redirect to url with action as delete and id to the record to be deleted
            window.location = 'Remove.php?action=delete&id=' + id;
        }
    }
</script>

So in short: 1st Table: everything works, all data gets deleted 2nd Table: Appears to be working but after confirming the Delete, the data is still there and didn't get removed from my DB.

The Code for Table 2 is exactly the same as the code for Table 1 exepct for the Names of DB and Table etc.

I am hoping you can go over my code see if you notice anything that might be causing this. Maybe if u agree with what I was thinking, that the same code will not work for both tables on the same page, that you can give an example or a link to how I can tackle this issue? Sorry for the Long code! Thank you in advanced!
