"Save" option not working with Keyboard

I’ve updated to Mac OS Monterey and since then, I can no longer get my keyboard (return key) to save a file in Audacity. Nothing happens when I hit the return key to save the file.

It works perfectly using the mouse to click on “Save” and on the following screen, the “OK” Audacity button works perfectly with the keyboard return key.

Any ideas why the keyboard return key wont work with the save option?

Screen grabs of what I’m referring to attached.
