After hard reset, contacts are missing and duplicated?

[Skulls138]

After I hard reset my 1520 earlier, I noticed some of my hotmail contacts are missing their Skype info. It comes up when they message me, but it won't let me reply. It uses their username as their number.
Also, I have duplicates. Sometimes up to 4 of one hotmail account, and I can't erase them. Is there a fix? Thanks. (I'm on latest build)
