It might just be that the requirement for them to show up is "have completed msq". Before you installed the expansion it counted as complete, cause hw msq was as far as you could get, once expansion was installed, msq was incomplete.
I'd just go progress the main story, you'll have to do that anyway eventually to unlock all the zones for your gatherers and crafters, then check back and see if the maps show up. If they still don't, I'd assume a bug and file a report.
