Protect individual menu items not showing menu items

My Membership Pro did not successfully import into Membership 2 - so I uninstalled and installed membership2.

As I go through, the menu does not display. I have checked the menu over and over and resaved it to be sure but it does not display in the protection area.

I have tried different menus and different memberships. Same result: 'No items available'.

Any help would be appreciated.
