Conditional menus with same pages

Hi,

I am using conditional menus to set up separate menus for my publicly available website and for my memberships.

I now have more than one membership and some of the pages are shared. When I am setting up the conditional menu with shared pages, even though I tick that the general condition is a logged in user, and the posts->memberships condition is ticked for the right membership, when I am on that page that is shared with another membership, the menu changes to the other membership and logs me out.

For example, membership 1 shares the page A with membership 2. When I click on Page A while logged in with membership 1, the menu changes to that of membership 2.

How can I fix this please?

The page I need help with: [log in to see the link]
