problem saving/exporting files

when I try to save/export a file the drop-down panel comes up where you would usually click on these options (name the file, export as MP3 etc.) but blank, so there’s nothing to click on. this happened a few days ago, and the problem was rectified after closing/re-opening Audacity and restarting my Mac but now it’s happened again and I have a file I can’t save or export. thoughts please.

PS I’m using OSX 10.11.6

pps and it’s Audacity 2.2.2

Audacity 2.2.2 is ancient.

If you want to stick with the old Audacity 2.x series, I’d suggest updating to Audacity 2.4.2, which is available here:
Audacity 2.4.2 is fully compatible with Audacity 2.2.2, but also has lots of bug fixes.

If you want to update to the latest version (Audacity 3.1.2), it is available here:
