Renamed global MarketPress tags and categories do not show up in sidebar widgets.

I have no way of displaying "edited/changed names" of categories and tags when using the global MarketPress widgets in my sidebar. Yet, names will display properly in pages using [shortcodes]. Is this a bug? Can it be fixed?

Currently I am using the global product tag cloud, but it only displays the old name of a tag, not the edited version.

Where in my database tables can I find/replace tag/category names?

Thanks.
