Guide not showing channels I subscribe to

This does not happen all the time, but it usually happens when I want to watch something on that channel.

If I want to see what’s on the golf channel and I open the guide and scroll down to where it should be (218) I see channels 219 and 217, but not 218.  If I arrow to the left and select Sports from the menu on the left I will see what’s on the golf channel, I can select that program, and watch it with no issues. I can also navigate to channel 217 and then move up to 218 with no issues.

I have had the same issue with CNBC and ESPN.

These are all favorite channels and I don’t have any filters on, I even see non-favorite channels in the guide

Have no idea why this would happen intermittently.

Anyone???
