Cannot record OTA channel

Channel 4-1 NBC is duplicate to channel 4-3 NBC.
4-1 doesn't come in anymore, but 4-3 does.
Problem is the Tivo only downloads scheduling info for 4-1 and not 4-3, so I am unable to schedule any recording for 4-3 NBC.
In the OnePass manager, I only have option for 4-1 NBC, I cannot chose 4-3 which is NBC also.
Any way to add 4-3 NBC to onepass record list?

 

Zip is 08876, 4-3 is a duplicate of 4-1, but 4-3 displays no lineup info - even though it comes in fine as NBC.
I have reported the issue on the form link you sent.
Will try repeating guided setup this weekend also.

 

4-1 freq 28 does not come in, 4-3 freq 36 comes in fine but without listing data - I reported this to tivo.
I have done a rescan of my channels, still same.
NBC moved from empire state building to world trade center recently.
Funny thing is I can get 4-1 freq 36 to come in fine when I do a signal strength test, but it doesn't show up on my channel list, I only get 4-1 freq 28
