Unable to add username

[kevinkk525]

I wanted to add my own repos so I typed in my github name "kevinkk525" but as soon as I got to my name, the "add" button disabled itself. I could add non-existent users but not my own username.

I tried so much that I finally got it working by typing "kevinkk525/" and then removing the "/" at the end. Then the button stayed enabled and it correctly started pulling my repositories.
