Vyper Dagger not displaying stacks

Vyper's dagger no longer displays the stacks above the target. It is purely visual; the ramping damage/movespeed penalty still stacks. It is still annoying because the visual queue is important. I believe this started happening around the Old Gods New Blood patch.

Melee damage also builds lethal venom on T3, and the tooltip says only bullets build it.
