Need help: contacts problem!

[pttptppt]

Hi guys! I don't know when this problem happened (I'm guessing with iOS 10) but all of a sudden, I have at least 50 contacts saying "No Name" in my contacts app. They have no info either, they're just blank.
Anyone know a quick easy way to delete them all? Going through each one and deleting is taking too long
