Not working with other YITH plugins

Hi,

We have other YITH plugins installed and 2 of them have filters in the sidebar.

The filters being used are brands and stock.

The filters are displaying fine on this page in the sidebar: https://gibbyselectronicsupermarket.ca/shop/

However they are not displaying on this page (accessed by searching with YITH AJAX search): https://gibbyselectronicsupermarket.ca/?post_type=product&s=sony

The pages are using the exact same widget and there is no javascript, css or php hiding the missing YITH filters.
