The likely cause is the way you have setup the site’s structure with cMap.
It appears you have multiple parent directory pages which use the category shortcode option to limit the list to a specific category. This is fine, but you also left the category select drop down enabled on these pages which allows the user to filter by the other categories. Since you’ve setup this up manually rather than letting Connections/cMap handle the category filtering, again, which is fine, but … you should disable the category drop down on those parent pages as Google will, at their discretion, follow the likes within a drop down. If you not sure what I mean by your parent category pages, here are a few examples:
To disable the category drop down select you need to add
enable_category_select=false to the
[connections] shortcode on everyone of your parent category pages.
After you do this, the other pages should eventually, at Google’s discretion, be removed from the search results. Fortunately this is only a few pages according to this search of your site:
Hope that helps!
