Menu issue

Hi,

Maybe I am misinterpreting how the menu should work, but here goes:

Creating a Portfolio Layout, I select Data source – Post.
Then I give three Taxonomies (which are actually tags) with relation OR.

When I look at the result, I see all the items I am expected to see, but the menu gives me two options: All and Blog. I don’t understand why I see the latter menu item – ok, tags are related to blogposts – because when I click that menu item, all the blog posts are being show and most of them do not have the three tags…

When I add a tag from a different category, same thing happens. I see the few items that have the tag, but immediately all the WP-categories that have posts with that tag become menu items. This behavior renders querying on taxonomies rather useless, since in the end through the menu everything on the site will be shown.
