I have added parts properties to a block and I have two BDD that feature that block. When editing the compartments the parts are only visible on one diagram even though the origins of the block are the same. I've checked the symbol properties to ensure that are no display settings preventing the display of parts. When opening the specification of the blocks on each diagram, the parts are simply not available on one to the compartment on one of the displayed blocks. Makes no sense given the blocks point to the same block in the containment tree that clearly shows the element's parts.

Why can't I show parts in one BDD but not the other?
