We dont seem to see all the modules that are set in the access group. For example we have one group that has access to most modules including Customs. The access is set to full but it doesnt appear in the list when selecting a module.
I'm not sure if this is still an open query, but if so, are you using Global Users? You will find them in Technics. If so, any Access Groups set up in here will override the one on the Person card.
