@theSLAYER Gotcha, that makes sense. Thanks for the explanation (and all the other resources and write-ups you've made available), it was very helpful!
@Steinn transfer moves from Bank aren’t retained when they are sent into BDSP, PLA, SV. They’re changed to regular moves. If you check the Pokémon under Bank View on HOME mobile, you’ll see the event moves. But those moves aren’t used by those games (unless they can learn it)
Anyway, moves on a Pokémon doesn’t dictate its event status most of the time. Having regular moves replace event moves aren’t uncommon. It’s more alarming if it had an event move from a different event.
