Parts shift during animation

[LaserMech1]

Hello everyone - I'm a part-time user of Keyshot and am having difficulties with doing a simple turntable animation. When I go to render it, some of the parts shift. The parts that shift are ones that I have imported from Creo. If someone could help me out it would be greatly appreciated.

Thanks

It is difficult to determine what is going on by reading your description. Can you share the scene by any chance?
