Loss of search function using Catalina

Using the recent update to Panorama, the search function is not working.
The first time after opening a file, if I use cmd-F, I get the search box and I can type in the search word, the drop down box will fill with the correct results, but will not select anything. The search window will close and all menu items but File and edit disappear, but re-appear when I click on the form or spreadsheet
If I try to use cmd-F again, nothing happens.
Essentially the same thing happens if I try using the menu for a search.
If I close the file and re-open it and can replicate the same process.
I have tested the file on a machine using Ventura and it works.
Is the only solution to upgrade to Ventura?

ProVUE does not have any computer with Catalina installed, so we cannot test this.

And mac tells me my system is up to date. I guess a new computer is in my immediate future.
