I have it working now. I uninstalled the snap version and installed the version from flathub. The submenus work fine now.

Thanks! I'll try it on my laptop, then in a VM as well.

Even with "Match", I end up clicking it numerous times, then all of a sudden, I get the pull down menu. I've been trying to make changes in the Post Processing area, but I haven't been able to get it to show its sub menu.

More feedback. It's hit and miss. I tried clicking "Clear" then "Load" but nothing. I tried it a number of times, then all of a sudden, I had the sub-menu of "Load Files" and "Load Folders"

I managed to achieve something in that after I clicked on the "Clear" button to the right of "Load", then clicked "Load", I suddenly got the drop down menu to chose between loading folders or files. So I can now load in a folder. Unfortunately, when I click "Match" I still don't get the dropdown ...

It's hard to show a screenshot since nothing happens. When I click on Match or Load, nothing shows. I tried to get you a screen shot, but all I could capture is the border around "Match" changing colour

Filebot does not show any of the pull-down menus in Ubuntu 26.04 (beta)
