 * It seems like deletion and ordering of elements is not functioning (see screenshot
   attached) in the latest release.
 * Console says:
 *     ```

 * Hey [@rsbl29](https://wordpress.org/support/users/rsbl29/)
 * Thanks for opening the ticket.
 * I couldn’t see a screenshot but I do see the log of the error you provided.
 * Unfortunately I can’t quite see what the issue is from that message.
 * Could you tell me a little more info about the issue?
 * 1. Where/how are you trying to create your template, directly in the block editor,
   via our template admin page, or the layout admin page?
    2. Can you confirm, you
   are able to add elements to template, but not re-order them? 3. Please add the
   following to your `wp-config.php` file: `define( 'SCRIPT_DEBUG', true );` Then
   can you check the error message again and share with me? This will give us more
   useful information in the error log you shared. * Taken from: [https://wordpress.org/support/article/debugging-in-wordpress/#script_debug](https://wordpress.org/support/article/debugging-in-wordpress/#script_debug)
   4. Can you try disabling all other plugins (and change to a default theme), temporarily–
   to see if the issue goes away? (then we’ll have a better idea of where to look
   for an issue)
 * Thanks

 * Hey [@rsbl29](https://wordpress.org/support/users/rsbl29/)
 * As I didn’t hear back from you for a while I’m going to go ahead and close this
   ticket.
 * Feel free to re-open once you have more information / if you are still experiencing
   this issue – I’m keen to get to the bottom of it!
 * Thanks
