SW motion study

[Letcic1]

Hello everybody
I need to make a small video from my motion study.
But I cannot make the spring contract when other parts in the assembly move. At the same time if I switch from "Motion Study" to "Animation" it works well and the spring rebuilds itself during animation.
Any ideas how to solve this problem?

P.s. if you download the assembly and play two animations you will see what I am talking about
