How to use the Manufacturing Stacking tool from Composites Design

I'm currently working on a file where I want to create the Manufacturing representation of my product and I'm following the few steps required (Create a new part body and set it up as the new main PartBody). When I try to do the manufacturing stacking (whichever the option I choose) I get an error message "Same representations has been chosen as origin and destination representation."

Any insight on how I can fix my issue?

Thanks
