live channel antenna grid incorrect

After a recent software update, the live TV antenna grid shows incorrect information for a number of channels. Mostly 2.x with some other scattered in the grid of 83 channels and sub channels. Note that titantv is correct.

I have tried everything suggested on the forum and elsewhere on the Internet; nothing has worked.

Specific errors that I see, there are probably more:

channel    displayd     actual
2.1              metv           cbs1
2.2              court          start
2.4             H&I              cbs-4
All of the 43.1-43.8 are incorrect.

The TV is
ONN Model # 100012589
Hardware ID H801X
S/N X02000T3HJLU
Software Version is 14.0
Device ID SOLGG323HJLU
Zip code is 10314

I tried connecting to both 4.2 and 5 GHz networks, no difference.
