Filter wipes taxonomy setting

I have the filters add-on, and it’s working well to filter by two taxonomies.

However, my results shortcode is set to only display posts containing a specific term from a third taxonomy: [ajax_load_more post_type=”post” taxonomy=”style” taxonomy_terms=”modern” taxonomy_operator=”IN”]

This works fine on page load. But the initial taxonomy/term selection is wiped when the filters are used – when all filters are deselected, it shows all posts, and no longer filters by the term I’ve set in the shortcode.

Is there a setting I’m missing or a filter I can use to ensure those results are always within that taxonomy term? I’ve tried the alm_query_args_{id} and alm_query_after_{id} filters but they just return the third taxonomy and ignore the filter selections.
