If the Tax Archive is showing the wrong sub-category structure, I’d first check how the categories are assigned and whether the parent/child hierarchy is set correctly. REHub supports taxonomy archives and hierarchical categories, so the issue may be related to the taxonomy configuration or the archive shortcode/template being used.
