Make Menu Available to Strangers

I love the plugin and so far everything is going well. There are excellent instructions. However, I am a problem with my stranger membership level. I want to make the menu available to strangers. However, whenever I add the menu to the positive rules it doesn't give me any options. I save it. However, when I go back to it again it's not on the list.

Background info: I have "Pages" in the restricted section and I've ticked off the few pages I don't want visible to strangers. However, it only shows the most recent 25 pages so I can't access a lot of the main pages that are in the menu. Would it make more sense for me to put the pages in the Negative Rules and just tick off the few I don't want them to see?

Thanks in advance. This is on the website:
