Remote back button is going to RDIO channel

I bought my Roku maybe about 7 months ago and have had the same problem for months now. I tried talking on here before and they kept telling me it must be the remote. Bought a new remote same problem. Then they said it needed an update but apparently it checks updates every day by itself. I have noticed that it happens mostly when I open Amazon and search for a video. As you type and you’re almost finished it jumps up and you have to start all over again. So unless I know the title of a movie I either don’t watch it on Roku or I start the movie on another device, open Amazon and look for it on the “Continue watching” area. But it’s kind of ridiculous that I have to do this for months now. Today I was scrolling through my settings on the set and it starting happening again, this time with vudu. It’s some kind of software issue but no one seems to want to try and tackle that. I might be going back to my Amazon stick soon.
