Unimplemented local channel

What does unimplemented channel mean? It is a local ABC channel and I am able to access it via abc.com through Xfinity. Any idea how it can be accessed through Channels? Rescan does not help. Different browsers did not help.

Just sent, thanks.

I also have a local ABC that says that. It comes up when you check the box for 'Local Networks via TV Everywhere'. Also on Xfinity. I figured it was just what it said, an unimplimented channel.
