I did a simple re-boot and got rid of most of my duplicates. Only WFFF is duplicated, but not with Regular schedule, it shows 44-1 WGBXDT, 44-1 WFFFDT, 44-2 WFFFDT2, 44-3 WGBXDT3, 44-3 WFFFDT3. There is no WGBX-2 in real life so that would make sense for it to skip it. It is only slightly annoying with the Nexstar blackout as when I type 44-1 it displays WGBX, but shows WFFF programming of course. I must press channel up to get WFFF to show, or select it directly from the guide. These two channels have always been fluky with my AM21; until the market was updated only WFFF -1 and -2 were in the database, but WGBXDT3 would automatically show up without me having to force a zip in for it where I had to force in zips to get my other missing subchannels. When they re-enabled the proper OTA scanning and the missing subchannels would show with their PSIP name and "regular schedule" guide data, WFFFDT3 did not do that and continued to show Create from WGBX instead of Bounce from WFFF. Not until the actual market update did WFFFDT3 override WGBX, but now they are both there.
