I cannot offer remembrance even with bowl

[Володар жаб ГУР]

I got 5 remembrances with my friend in multiplayer ( he is the host). I can only offer Pieta remembrance to Mohlu. Is there any way to fix it?

did u kill other boss solo? i think u need kill all main bosses together

need to have progressed and killed the bosses in your save.
Not sure if shared progression fixes this, but I hear it's buggy
