Why my Trigger Box does not working?

Hello, every one.
I know my English is not good enough. I apology for that.
So, I have a trouble.

I’m trying create a VR Level.
I tried to moving a pawn at the trigger box event.
Specifically, when the pawn overlapped on the Trigger Box, active the Time Line that connected to the Add Actor Local Offset.
It’s worked before. but, it doesn’t work after change the Default Game Mode.
My Game Mode settings is fine.
I don’t set a Add Movement Input, because I don’t want to move the pawn by the operation of the player.
