IOS 8 - Permanent Disabled location in My Friends

Hi.

I used the Shared Famility functionality and it works as expected with itunes, apple store, photos, reminders, calendar and Find my Iphone.

When I use the app 'My friends' I can see my wife's location, but she can't see mine.

When I access app My friends, the bottom area displays that I have my location disabled. But when I go futher I have my location shared (in My friends app and also in iCloud), and I have also enabled in the privacity > location area.
