Strange Behavior: Always the same "first episodes" of certain seasons added "a few seconds ago"

I have a TV show Plex library (using the latest PMS 1.33) and I have enabled the feature that my library gets scanned whenever something is added to it.
I am using the TVDB agent to scan it.

However, I just saw that something is not okay when I changed the “view” of my library to show me episodes and sort the by “date added” (showing the most recently added episodes first).

Then I saw that I have 15 different episodes being listed as being added “a few seconds ago”. No matter when the last scan was!!!

Furthermore ALL of these fifteen episodes are S0xE01 (first episodes) of different (but not all of these) seasons of 10 different series. Always the same episodes showing up as being added just a few seconds ago (while all other episodes) are listed with their true addition times.

Finally, I noted that the date of last change of these movie files was set to 2022. :frowning:
I changed that date of last change for all the files and refreshed the library.

I thought that I will be fine, but no…
The 15 episodes are still there at the top of the list.

Obviously, the date of last change is somehow related to it, when the files are added (instead of the actual date when the movies get added), which is wrong IMO. Plus, this date is not forgotten once added to the library and taken into account even if it changed.

A) How do I fix this?
B) Please somebody fix this behaviour of the metadata scanner in a future update. Never use the date of last change as a reference to the addition date, but the actual date when I add this movie to the library.

Thx

Plex Dance the affected episode files.

Moving them elsewhere, doing library refresh, moving them back with the corrected date was enough.
