Speed doesn't update!!

UE suddenly decided not to update speed value while standing. Everything was working great. I was working on retargeting the skeleton mesh when UE just stopped updating the speed value. Where do I start debuging?
The project is based on the sidescroller. When I test the original sidescroller character it works fine. I double checked the input setting, anim graph and the movement BP in the character BP. Everything seems normal.

Any suggestions? (A part from starting over because I already spent 3 months developing the characterBP)

the use root motion from everything caused the problem. For me Use from montage only was the solution.
