Return of Reckoning

I have my full dominator set on it and still can't buy oppressor cuz it says my tome is locked.
Checking out my tome it says I have all 5 pieces of dominator.
I already have 4 pieces of oppressor cuz i bought it like 1 week ago with no problems now suddly asks for tome unlock.
Please help I'm almost finishing my oppresor.
Screenshots of all my set equiped and all tics for dominator.

Well it seems it was only a visual bug asking for tome unlock and I spent all my warcrest on the same item... thanks to that bug...

I got rly disapointed with this game after that but thanks all it was fun
