Channel/Frequency Issues

I recently purchased a Roamio ota, just ota no cable, and I am having an issue getting the guide to work. I went through the setup and entered my zip code and then scanned channels.
The guide for the channels that tivo says I have based on my zip code are all correct, but when I do a channel scan all my channels come in on other frequencies. Therefore my guide wont work.....it just says "title not available".

I was wondering if there was a way to edit the frequencies for the channels...
