Photoview rendering with Motion Study Leaves Subassemblies Behind

Hi! I'm sure I'm just missing something silly, as I am just beginning to learn solidworks.

When trying to render a subassebly moved by another component in a motion study, photoview renders the subassemblies as left behind in some cases, or blown apart in others. The study without the rendering seems fine. Anyone know how to fix that?
