Ah, thats because you need to invest cores to unlock every level of the deep wounds/despair/assassin mastery. You should know this since you upped assasin twice right.
If you invest cores to unlock another level of the masteries but dont put any points in it yet, it should be yellow as usual.
They are black because you can not put ADDITIONAL points into them until you unlock the NEXT levels. They are currently being applied, but just at the levels you have in them so far.
It is hard to see in game that Deep Wounds is working or not (assume it works for you), but Scouter Lens should be easy for you to verify if working or not.

OK, just to make absolutely sure, you pressed unlock at this stage correct?
