I have two contacts in my Live Mail Contacts list whom I'm unable to edit in any way! 

As you can see in the screen shot (trimmed for anonymity), although I have one of the contacts highlighted, the Edit and Delete buttons are not available. All the other contacts are ok in this respect. How can I edit/delete these two rogue contacts

However another niggle is that I've renamed some of my contacts to make them easier to find and although I've changed the name, when I enter them they display as the original names and not the new ones. I think this has been captured in other threads, but don't think it has a satisfactory answer yet?

Thanks,

Jac
