Reappearing suppressed components

I have several conigurations in an assembly  of a 10 row bleacher stand. When I sometimes get into one of these cofiguarations, components appear that were

previously suppressed.

Is that because these components are in a local pattern and when I move from one configuration to the other they  reappear?

I have been suppressing components with the pattern itself not the whole pattern. I am using SW 2010
