That's in an area that didn't get rid of the old duplicate HD lineups. Most places started their HD in weird spots, and it wasn't until too recently where they sunsetted the old spots in the 200's (or wherever) to standardize them in the 800's (or 1000's depending on area).
In Philadelphia we have HDs in the 200s, 800s, and 1000s, and it's super annoying. Especially when trying to set up favorites lists on the iPad because it picks up all instances of the same channel.
