Ticketing App bugs

Hi, this is your own Ticketing app (from your examples) that I am using. Now if I try it, it allows me to view a ticket but it does not allow me to edit the ticket via the dropdown menu. It generates similar errors. Here is the link. Anvil | Login

If you still want me to share a clone of the app, please tell me how to do it. I am a newby.

Thanks.
