Applying 2 curses not working with Pride

I have You can apply 2 curses on my body armour
I have curse enemies with Vulnerability on hit on my ring
I have mark on hit + Assasin's mark as gems in my boots

When i hit rare/unique creatures I only see vulnerability curse on their heads. I messed around with it and it seems like I can get both curses when I turn my Pride aura off. Is there anything I am missing here about Pride that stops me from applying 2 curses?

I figured it out, I just didnt have enough mana for it lol
