Cannot remove play session from game or game from recently played

[Rings4]

Removing a play session from a game (clicking the X under Actions) removes the session and thus removes the game from recently played when that was the only session, but restarting playnite mysteriously brings it back with its session as though you never deleted it.

Annoyingly still here

Closing out, game is still there

Clicking the calendar button now shows no sessions

Going to a different window and returning to GameActivity shows game is gone (as it should be)

Closing Playnite and opening it back up shows all removed games mysteriously back. I did the same to all the other new games that are in this screenshot. They keep coming back for some reason. I want them gone.
