contacts list

New Email
Up until last week, I could compose or forward an email by clicking the "to" box and type a single letter like "M" and all the names with M would appear in a list that is in my contacts list, then I could click on it and it would insert that name in the send to box. Now I do the same thing but names that i deleted years ago that have nothing to do with my contacts list appear not my contacts list. How do i get my contacts list to work again?
