Guided search meltdown.

using drupal 6.68 and faceted search 6.x-1.x-dev
the guided search shows an odd 'breadcrumb' with ALL the options (instead of just the currently selected option as it seems it should) and when chosing a facet, it adds a 'default' value the previous facet in the enabled list
attached is a screenshot of what I am talking about
