Moving from Grid Mode to Loupe Mode NOT changing selection of photo

• Beginning in grid view I select a photo, photo #1.
• On photo #1, I edited then exported.
• I go back to grid mode and find another photo to work on.
• I then select a new photo, photo #2.
• I go to export, it is trying to overwrite the previous file using the same name.
• If I proceed and overwrite, it replaces the file photo #1 with the same one, photo #1.
• If I double-click the newly selected file, photo #2, to enlarge it, it brings up the previous file that I had worked on, photo #1.
• Once I have the photo #1 up large on the screen I move over to the photo #2, while still in loupe view, I can then export it correctly. 

• I then go back to grid view and select a new photo, photo #3. If I attempt to export it, it overwrites the photo #2, with photo #2. 
• If I double-click photo #3 to go into Loupe mode, it brings up photo #2.
• This continues as long as I use this routine.

• To break the routine, I have to go to loupe mode to select a new photo.

This is also causing problems with editing title and caption. I’m getting data from previous photo overwriting data in new photo IF I am in grid mode.

Seems that whatever I do in grid mode applies to the previous photo I worked on in loupe view.

Whatever photo I was last on in Loupe mode is the target of whatever I do when back into grid mode.

I have closed down Lightroom and saved, tested and optimized the catalog, but it still happens.

Thanks for any help.
