The Demon Slayer trophy dilemma

Trophies are super glitched anyway. Can't get the Legendary Participant trophy on my mercedes even though that's one you get simply for accepting that one quest. Legendary Artisan doesn't seem to want to activate either.

You get Legendary Participant for completing all of Gaga's junk collections.
You get Legendary Artisan for leveling up a profession. (If you were already at level 10 when the event started, you need to unlearn them and learn a new one and level it, at least once).
