[nextgen-gallery] page links are not removed

Ok, here’s what I do:

– add a new gallery
– upload pics to that new gallery
– i want the pics to appear in a new subpage from an already existing page so I go to the gallery settings, select the proper page at the ‘create new page’ option and click the ‘add page’ button.
– So far, everything’s fine. However, when I remove the new gallery, the new page isn’t removed. It’s still shown in the header of my website and when I click it it says ‘[Gallery not found]’. Which is true of course but I want that entire page to be removed as well. How can I achieve this?

I use WordPress 2.9.2 and NextGEN 1.5.

Thanks!
