keys reverse with LoadLevelAdditiveAsync loadscene

Hello, I have a problem during the development of my MMO I use LoadLevelAdditiveAsync to load my scenes here is the schema

I have a Network Manager scene (blank) that I use to load my other scenes with LoadLevelAdditiveAsync
I also use the ThirdPersonControler prefab of the standard asset however I don’t know why my controls are like reversing during scene loading (the character moves to the right when I press left etc)

I don’t have that problem if I only use the scene with the prefab

problem solved I had 2 main cameras
