Virtual Channels bug?

New channels user. I love the virtual channels feature. I don't know if anyone else is seeing this. When I use channel up-down it works fine until I get to a virtual channel. My virtual channels start at 201-207. I can be on cable 200, push channel up, and it will go to 201, once on a virtual channel if I push up to go to next virtual channel or push channel down to go to the next lower cable channel, Nothing happens. I have to enter a number or navigate via guide. I can enter a number. Tune it then get back to a virtual channel with a double press on play. I use Nvidia Shield as a client. I'm not sure if this is a bug or I just have something set up wrong.
