VR multiplayer bug when controller possess a pawn on open level!

When i use open level with option “listen”, and when the level actually loaded, there will be about 0.2-0.5s that the controller possess the default pawn before they possess the right pawn that spawn by game mode. If i dont use VR, it will be fine, but when i use VR, it stuck with the default pawn, althought my pawn that i set in game mode spawned in the level. And im using version 4.16. How can i fix this bug?
