Paper 2D rotator 180 degrees doesn't work

Hi, I’m followng a video Paper2D: Movement | 06 | v4.4 Tutorial Series | Unreal Engine - YouTube and i have changed the Make Rotator instead of Yaw 180 it’s still not working.I also tried to copy the 2dsidescrolle project it’s still not working for me.
Where can i search for it ?
