Collapse Trajectories issue with moving bones

Hello,

I have been working in 3ds max in Unity for years now and I have had a lot of my questions answered from these forums. However, this is one problem I haven’t been able to figure out. My animations works fine but when I select the bones and go to the motion panel, and select collapse trajectories, the whole animation screws up, every bone moves out of place and nothing is where it is supposed to be. Has anyone else encountered this problem??

It is happening to me too, collapse even deforms my model.
