P: File extension (ex. jpg) not changing during format change after upgrade to macOS 10.15 Catalina

What the hell is going on. This will delay my work tremendously. Is there any PLUG IN to help with this failure?

It appears that with yesterday's installation of Catalina on my Mac, Photoshop is not saving to the proper file format.  When attempting to save a .tif file to a save as .jpg file, I choose the JPEG file format in the dropdown menu, but Photoshop doesn't recognize this and saves the file as a .tif file, then sends me a warning message asking if I want to replace the .tif file with the new one.  I have to manually delete the .tif extension and type in .jpg for the file to be saved to the proper format.  Many times, and this was well before installing Catalina, Photoshop also saves a file to a previously opened folder rather than the one I am working on, and I have to search for the saved file.  MADDENING!  I did see several posts regarding the file save issues, but this has only happed to me since installing Catalina yesterday.

Since I updated MacBook Pro to OSCatalina and also Photoshop to latest version 20.0.6 (both same day) I cannot save any file to pdf format well. And by well I mean that every time I try to save any file to pdf what it does is save it with a .psd extension (but it is actually a pdf). Thing is I already lost to layered master Psd files because of this bcause when it asked to rewrite the file at saving (thinking it was an old pdf) I accepted. Meh! I lost the original.
