Blutility context menu popup shows all pins inside function

ActorAction Blutilites are showing all pins inside a function.

This does not happen with editor callable custom events.

Also occurring in Main/4.21 CL #4221482

1. Enable Blutilties in editor preferences
2. Create new Blutility, and select ActorActionUtility class
3. Make a function with CallInEditor=True, and one function input
4. Add logic with for loop (image attached)
5. Right click on an actor -> Scripted Actions -> run the function.

Result: Variables from for loop will be shown
Expected: Only input variables are shown
