Help with mates when using motion study

Hello, I'm new to solidW.
Trying to figure out stuff, but i'm stuck with a mate and motions tudy issue.
I'm using mate controller, and I simulate the motion in it perfectly with no issues. Also in Model View the same I can rotate, and move everything is fine.
But as soon as I start using motion Study. it dont matter how i do it if import the mate controller info or just angle by angle.
The angles seem to flip. so the motion is incorrect.
I ahve been reading but did not find a solution, did find that flipping is an issue in SW, but if anyone can help on how can i make the mates more stable i appreciate it.
Thank You
