Weird technical info in screen corner whenever streaming content

Just got DTV satellite with Gemini combo service 2 days ago and today some weird technical info appeared in the corner of the screen whenever we stream Netflix. We’ve turned the TV/Gemini on and off multiple times (waiting 10-20 seconds before each power in) and it won’t go away. Wasn’t there yesterday or the day before. We haven’t set up the rest of the apps yet so haven’t tested if it’s across the board for all streaming or just Netflix.
