What's happening here is this: I have more than one account and they all are displayed with they're display names but in the moment one gets new mail, all names turn to the one that got the mail.
Exemple. No mail: "XXX" "YYY" "AAA" "BBB"
Now, a new mail enters "YYY" Display shows:
"YYY" "YYY" "YYY" "YYY"
