Importing back into LR

[Activating_Lightroom]

I'll export a number of Raw files into PS layers and after working on I'll save and close expecting into to find the PS file back in LR. Sometiome it's back and sometimes it's not. In the library It shows as an extra photo in my folder but it's not showing for me to work on further unless I restart the application.

Any help would be apreciated as it's hap[penned on every version I've used.

Are you using Lightroom Classic? What version NUMBER?

Are you using the "Edit In..." command in Lightroom Classic, or are you really doing an Export from Lightroom Classic?

Your title says "Importing...", do you really Import the photos back into Lightroom Classic?

Classic 9.2.1 the latest but this has happened on every version. Edit in - open as layers in photoshop-in PS save and close when finished-back in LR.  Fine at times at other have to restart LR.  Not just PS, any other program, at the moment Ricoh stitcher exactly the same.  In Libray it shows extra file under keywoed list but can't find the worked on file. Thanks for your help.
