Why are there 3 phone applications in my application manager?

[9nine9 Nevermind]

There are 3 icons of "phone" in my settings under application manager... why are there 3 of them?

Because this is how Lollipop is. Why? No one knows, but it's nothing to worry about. It's normal for LP. Previous OS Kitkat, only has one phone app.
