OnBeginCursorOver/end is triggering multiple times per second even when not hovering away from actor


I’m trying to create target health bars for a topdown ARPG where the health bars appear when hovering over an enemy or npc. I set it up with onBeginCursorOver and onEndCursorOver. The target bars correctly display the name and health of the hovered actor but the problem with it is that it “flickers”. The onEndCursorOver is triggered multiple times per second even when you don’t hover away from the actor…

Any ideas what might be wrong?

Thanks in advance!
