Deleted Images Remain Gray and Syncing
I upload about 2k photos from each sporting event I take, so I can do all my corrections in Lightroom (v 4.4, build 20210805-0652-b84a95f), then transfer/upload into my Smugmug photo site for sharing/viewing by our school families/athletes. I typically delete hundreds of them (permanent deletion using option+delete) as I work through them in Lightroom, so the only images that upload to Smugmug are those ready for viewing/that I want to share. (I am working on an iMac, macOS Mojave 10.14.6)
In a perfect world, they gray for a few seconds then disappear (as they should) from my album. Lately, they remain gray. Lightroom continues to sync and function, but they never go away. I can continue working, but if I then go to upload to my Smugmug site, it will upload even the ones I "deleted." If I close Lightroom and reopen, all the ones I deleted are still there, and I have to start all over - going through each photo again to remove the ones I don't want in the album. Again.
(1) I know the difference between deleting permanently and just from the album. The same thing happens either way.
(2) It doesn't happen all the time. Sometimes I can get through multiple deletions, but once one photo remains gray and doesn't drop out of the album (delete), all subsequent deletions will do the same thing. (So I have to stop, close out of Lightroom, and start again.)
This is adding a TON of time to my processing and duplicate work. What is going on and how can I keep this from happening?
