Alright I just tried all my steps. Here is a screenshot for each steps.
I have this smart playlist I want to edit the filters.
I added a few more artists name I don’t want in the playlist.
I hit apply and check the filters again. All good.
I hit save then come back. All seems good. But now I add one more.
I hit apply then save. All seems good. But then I go back to library and edit the filters again, 3 filters disappeared
