Yeah, removing a version shouldn’t have reset that recently added reference.
Did your art and watch status stay the same and just the “recently added” aspect changed?
If you move titles around while automatically delete and autoscan is enabled it can do funny things so turning that off can help. Maybe check that and see if it treats it differently?
One thing you might check, as it’s come up in a couple areas now about poster resets, is the KEY field is changing on them. Video ratingKey="70780" near the top if you do Get Info and then View XML on a title. That field is a unique reference that is incremental as you add titles (you’ll see it repeated in your metadata references and such). If you look at titles you added recently and ones that you added in the past and then compare it to the old titles that suddenly showed up in “recently added” you can check and see if Plex reset your key. It shouldn’t for titles that already exist in the same library.
But I saw recently with changing subfolders around it doesn’t always work right. I keep titles in bulk folders and tested fixing that by created title specific folders within the loose file bulk folders (all in the same library). When I moved a title from bulk area into a “Movie Title” folder it worked fine no problem (transparent change in Plex). When I moved that title back out from “Movie Title” folder it reset that key and showed up as “recently added”, but kept my art and watch history. It shouldn’t have reset that key.
I reported a different poster issue than the one in that thread and they asked about that key resetting (it wasn’t in my case) so this might be another example of that key resetting when it shouldn’t be … but it might partially be from the autoscan\partial scan\auto delete so if you have more titles you could try with those settings off that might help with providing more detail about where the bug exists (and workarounds to avoid it).
100% shouldn’t be resetting just because you took one version away. I’ve removed versions all the time - just removed like 100+ - and didn’t have a problem but those versions were in the same path (4k\1080p both in same folder). So your example and mine where it did change the recently added status both indicate some path management issue might be at play.
If you confirm that the key did change, maybe ping Atomatth (don’t want to ping yet) as they were helping in that other key changing thread and this might be useful additional information for them to gather for it.
Edit: I lied… it did reset my artwork on that key reset on that one title I mentioned (it was just using the poster that matched what I was already using so I didn’t notice it until I just went to confirm). It kept my watch status and watch history but did reset the artwork which makes sense as that’s tied to that key.
