When animating all subcomponents merge

[Anonymous]

When I go into the animation workspace all of the subcomponents disappear, everything merges into one component.

I attached a video that demonstrates the problem.

Your model is made up of only Bodies, you need Components to use the Animation Workspace.  You can create Components by right clicking on each body and selecting Create Component from Body.  You will probably need to add Joints to your model after doing this.  You can be able to use As Built Joints to speed things along.  You can attach your model if you need help with this.
