mounting the engines causes the "engine_name" to be prefixed with the namespace. So katalyst_content.root_path would resolve to admin_katalyst_content.root_path. This causes issues as internally in the engines they refer to katalyst_content etc.
Moving the mount into a scope so it only affects the route not the helper generator
