Shows recording on wrong channel

Some of the shows I record have started recording on the wrong channel and therefore not recording the correct episode.

The Atlanta Braves had been recording from Brave Vision (645) fine until this week.  Now it is trying to record it on MLB Network, which doesn't play the games locally.  So it's recording other teams but not the Braves.  Incidentally, I don't want it to record other teams on MLB Network but it has somehow defaulted to every team which means I have to delete 32 different settings.  I just want to record the Braves on Channel 645!

My wife is having a similar problem with Jenna and Sheinelle.  There is a replay every day of the morning show on something called Today Show Channel (?).  The problem is the name of the episode is for the next day even though it is a repeat of today's episode.  So when today's episode plays it doesn't record because it thinks it has already recorded it.

I know that you used to be able to specify (only record on this channel).  Why has this feature gone away and when will it come back?  This is a mess that should easily be fixed.
