Are you referring to your Ion subchannels? How about your main channel which (at least in my neck of the woods) is in HD and shows Digital Service? The guide data worked fine for us in the DC DMA before the transition.
I just reloaded all the channels. I don't watch ION or many of the other channels that I get OTA, so I had them deleted. It takes a bit of time for the data to load so, when it loads I'll answer your question.
