Playing v.1.9.0 on PS5pro.
I started a new run on story mode till beginning of Episode 2. f 2, c_0 not unlocked.
Also problems with f_0, c_4 unlock for … starting the story mode. It now unlocked, but after using another story mode slot for playing one of the mini games and going back to arcade, the unlock was gone.

My main issue here is, that it seems I can not unlock certain songs, that are tied to challenge board unlocks like character unlocks …

Edit: If you completed the story, all of the mentioned challenges should be cleared, should.
