If they weren't in the lineup, it would screw over all the people living in the outer portions of the markets who can receive those stations.
Originally TiVO was using Gracenote/Zap2it for data, but after TiVO purchased Rovi, they switched to their data in 2016. Gracenote provided zip code specific OTA lineups to take care of all those outer areas that got neighboring locals, but Rovi just provides one OTA lineup for the entire DMA, so after the switch TiVO had to start including all the extra out of market stations so no one in those outer portions would lose listings for the neighboring stations their antenna picks up.
i.e. in my DMA Scranton, the eastern parts of the market can pick up Philly and NYC stations, the southern parts of the market can pick up Harrisburg and Philly stations, the western parts of the market can pick up State College stations, the higher elevations in the northern portions can pick up Binghamton, Elmira, Syracuse and Utica, so TiVO's OTA lineup includes all of them.
In a perfect world Rovi would overhaul their OTA lineups to be zip code specific, which people have been begging them to do since the Gemstar days, but for whatever reason they stubbornly want to stick to single OTA lineups for an entire DMA.
