The Knifemaster rogue isn't getting his five percent slashing resistance, though the set of knives appeared on reset.  Tried resting and using the reset perk option, neither works.

Know what it is, will fix it when I get the module next. Bruiser suffers from the same.

Let me know if the knives you get suddenly is added to other stacks.
