A live select filter on taxonomy (category type of project) of a a custom post type projet (project) was working in previous Bricks version but not anymore.
I have to add a filter submit element (with reset option) to make it work.
I have the same problem and found a work-around:
Adding a filter submit element and setting Filter Select element to “apply on input” does the trick for me. You can set display:none on the filter submit element.
