To follow this problem, it is a bug known by solidworks (response of the axemble hotline). There is a workaround that is really time-consuming and tedious to set up.
I can confirm that this problem still remains. This animation module, if it gives a glimpse of many possibilities, is nevertheless full of problems and bugs. It is time for SolidWorks to focus on the real problems in its updates, which are for the moment mostly cosmetic
