tl;dr Does SF Pro support shared taxonomies and if not, point me in the right direction?

I’ve got a custom taxonomy being shared across 3 custom post types, with taxonomy term archives rewritten using add_rewrite_rule to use /cpt-base/shared-term, /cpt-base-2/shared-term, etc. These are working as expected, showing only those custom post types with the specified term. The taxonomy is registered like this and the rewrite looks like this.

Each CPT has its own SF shortcode set to Post Type Archive (mainly to sort by post meta/date) and most importantly, Enable Filtering on Taxonomy Archives is checked so the filters work on the taxonomy term archives too. For the custom post type archives, and the first post type’s term archives, everything works great.

Here’s the problem: when Enable Filtering on Taxonomy Archives is selected, $wp_query->query_vars['post type'] for the remaining taxonomy term archives gets set to the wrong post type, even though $wp_query->query['post type'] is the correct post type.

Here’s a var dump of $wp_query for a term archive for the first CPT, which works fine: https://cl.ly/lXEV
Here’s a var dump of $wp_query for a term archive for the second CPT, which shows for wp_query->query_vars['post_type'] incorrectly set to the first CPT: https://cl.ly/lWVk

When the forms are deactivated, or the taxonomy filtering option is turned off, the correct posts show up on the archives. I’ve tried turning off AJAX, no difference.

Side note: I can confirm that the correct form shortcodes are being added to the correct post type archive and taxonomy term archive through conditional statements. Since query_vars is not returning the correct post type, post_type_archive() and get_post_type() conditionals don’t work, so I’m using if ( 'post_type_name' == $wp_query->query['post_type'] ). Also, all posts are using archive.php.

Last thing: I also tried using sf_edit_query_args (gist) to set the post type but it didn’t seem to work and just caused more problems.

Hopefully I’m overlooking something easy!
