Problem description

When trying to edit the logic of this object, the editing section of the page went blank with a “Opps! Something went wrong” error. I tried to refresh the page, log out and back in but the error was still there. Once the error went away and the page showed again, all the logic I had on that radio button was completely missing

Steps to reproduce

Please describe steps to reproduce starting from the first action.

1. On the ‘main’ container, Capture-Fish-Data page, summary_selectionradio ID
2. Opening logic gave the error mentioned above
3. No longer shows the error but all the “on change event” logic is missing
