Favorites Won't Stay "In View" on Guide

[#1]

I probably didn't word that as best as I could. But, I've had FIOS for 2 years or so, and up until a week or so ago when I clicked on the Guide, it showed the guide for the channels that I have seleceted as "Favorites 1" - then, I noticed it has switched to "All Channels". So, I clicked the heart button, changed it to Favorites 1 and selected a channel. Next time I hit Guide, it had gone back to All Channels. 

What's the deal? How can I switch it back to my Favorites - and have it stay there?

For favorites to stick you have to have two things enabled.

Menu>settings>television>modes = enable

Menu>settings>television>last guide state=Enable

and now favorites should stick

The exact same thing is happening to my favorites. I click on it, get the text that it's on Favorites 1 and when I pick a channel it goes back to All Channels. Very irritating but I can't figure out how to fix it so far. 😞

That did fix it...thanks. It was really odd that it suddenly had a glitch like that after a year of keeping the Favorites selected. Ah well...it's fixed now. 🙂
