Bug: I still receive Perk Points after having max amount

Hello, I have fully upgraded all my perks, and the perk point counter in the upper right disappeared, but whenever I finish the highest-realm challenge, I still get a message showing I got 10 perk points. Not sure if this is intentional, since one of the patches said that the maximum perk points you can ever have is 1550?

EDIT: Now I get Piety, so I assume some Specializations required more Perk Points than my current one?

Warm regards,

Yeah, 1550 is the max, but some only require around 1500 or so, probably including the one you were using at the time.
