Need Help with the Calculate Direction Node

I have a Problem with the Calculate Direction Node. When the Character is in Idle, the return Value is 90 insted of 0. In my Blendspace the x axis is setup from -180 to 180, and the Idle Animation in on 0, so my Character does not stand still. Can anyone Help please?
Thnx…
