          INNER JOIN "katello_content_facets" ON "katello_content_facets"."id" = "katello_content_facet_errata"."content_facet_id"
               WHERE "katello_content_facets"."host_id" IN

                           IN ('Host::Managed') AND "hosts"."organization_id"
                           IN (1) AND "hosts"."location_id" IN (2) AND (("katello_host_collections"."name" ILIKE '%Test Hostcollection 1%'))) LIMIT 6)
                      subquery_for_count

Expected results:

It should show the dashboard

Additional info: 

There is a work around for this. In step 5, if we use '=' instead of '~' in "Host" filter, it works.

5. Host : edit_hosts, build_hosts, view_hosts
   Filter: host_collection = "Test Hostcollection 1"
