That is a Tablo design flaw. They can’t handle two stations with the same virtual channel number. See my posts in this thread. Station Mislabelled in Guide
For Las Cruces zip 88001, Gracenote has guide data for all four of the subchannels for KDBC. And for two of the seven subchannels of K42DJ (aka K22NM). But the Tablo developers don’t know how to match up the guide data to the right station.
