Blasphemy doesnt work in demon mode PS5

So the UI on the consoles is different than the ones on PC. Because of that i cant asign Blasphemy to the "weaponslot" for demon mode. As soon as i swap into demon mode blasphemy disapears. I didnt find a specifict tread for this issue so i made one just to be safe. I have more than enough spirit, the removed spirit from the weapon when entering demon form is not the issue.
