issue with custom menu's for logged in users vs not loged in users

i am trying to set up a particular menu where logged in users can see specific pages such as registration page and hide others such as make an appointment, I have tried to use the membership plugin under membership access levels and setting a positive rule to allow one type of user a specific menu structure. This was not working, after searching for another solution i found wpmudev’s post here: https://wpmudev.com/blog/wordpress-show-different-menus-different-users/

that suggested using a different plugin, i installed and activated this and tried to customize it as above separating specific pages for logged in vs not logged in. however it seems only to work for either one or the other and not for what i need. please could you advise on what would be the best way to fix this issue?
