Mine currently does same, and I was able to create this behaviour by adding multiple sequence nodes all adding new widgets (see MyCharacter event graph).
My best suggestion is to look at MyCharacter event graph and try removing some of those sequence nodes to add less widgets, it seemed to alter behaviour.
To be honest I kept seeing different behaviour (no nodes animated, only partially animated, only some nodes in sequence animated, only animated when focused on scene) and it is very inconsistent to try and reproduce.
Unfortunately I can’t really give a solid set of steps as its so inconsistent.
