The Powerlink Search box is removing the filters on my Listing page.

If the dealer has a modified Powerlink, ending in ?f_make=Honda for example, to only show Hondas on the page, the filter to limit the page to Hondas will not remain unless 'Make' is added to the Search criteria in the Powerlink Search settings page in IVM or Insight. If 'Make' is not an option in the Search box, it will revert to All if another Search option is selected.
