When we use a filter on a section we only see what is tagged with that filter ....yes ?
now then if we use two filters we see what is tag with either filter ...yes ?
I propose that if we use two filters then we only see what is tagged with BOTH filters .
aka , blues returns all posts tagged with blues .
VA returns all posts tagged with VA .
VA and Blues returns posts tagged with either Blues OR VA .
I submit that VA and Blues should return only posts tagged with BOTH Blues and VA .
