After Rendering photo slide show pic's shift why?

Okay Adobe world,

Can someone please tell me why my photo slide show images shift and pan and zoom on parts of the photo I didn't originally set? Driving me nuts after hours of work and during playback the pan and zoom are all off line.

Are you not able to pan and zoom while using a transition between shots?

Do you need to set the pan and zoom before adding a transition?

or

Are you not suppose to user pand and zoom with transitions on the same image.

Thanks,
