Pages published by the rsp plugin does not show up in the Add Menu Items box list or search function

After updating the resellerspanel plugin, my custom menu disappeared. Now when I try to recreate it, I can not find all the pages in the Add Menu Items box. not in the View all-list, and not via the search function. An example is the page Data Centers. It does not appear under View all, and it does now show via Search, so I can not add that page to the menu. The page is published and is live on the site.

What can possibly cause that?
