No control over display Menublock with Menu Trails

Issue Summary

I'm having trouble displaying a Menublock containing Menu Trails on the proper pages.

In this case I only want the Menublock to be displayed on pages that have "Referenties" (References) in the first arg of the menu. However, it's also being displayed on the News-page (having "Nieuws" as the first arg in the url). The reason for this could be that they're using the same taxonomy. It's being separately used for "related items" (be it related news and related references) in basic content nodes.

The term parents in the Manu Trails "Categories"-configuration are all set with "Referenties" as the parent item (screen). This makes the Reference page (and its nodes) work well along with the Menublock (containing "Webdesign & development", "E-marketing" and "Multimedia" as menu items) and its generated breadcrumbs (screen. But the problem is that the News page uses the same taxonomy, and therefore displays this Menublock on the News page as well while it shouldn't. On top of that it displays the wrong breadcrumbs as well. So basicly the Menublock with Menu Trails and related breadcrumbs are on a page where it shouldn't be displayed (screen.

When I configure the Menublock settings in "Admin > Build > Block" > only display on these pages: "referenties/, referenties/*", save it and clear the cache, nothing seems to have changed. It seems like the Menublock is not following those settings. When I make changes in the Categories-settings of the Menu Trails configuration it doés seem to respond to the changes.

So somehow the Menu Trails configuration is overriding the Block settings. Is there a way I can get control over this behaviour? To be more precise: is there a way I can avoid the Menublock with its Menu Trails to displayed on the wrong page (i.e. the News page), eventhough both nodes are using the same taxonomy?

Kind regards and thanks in advance.
