Comment:

 This indeed seems to be a caching related issue. It is the expected
 behavior for posts (in this case based on the menu items) to fetch the
 metadata if it hasn't been loaded into the cache yet.

 For large sites or sites with very complex requirements (a menu with 80
 items is not quite common), the recommendation would be to use a
 persistent object cache indeed.
