Is anyone able to view Masters 4K programming on Channel 106? Masters 4K 15 & 16 appear in the program guide, but when I select the channel the only thing I am able to view is the Directv logo. I have no problem viewing 4K programming on Channel 104. I have refreshed the signal to the box, and have done a red button reset. The problem still persists. The only 4K channels currently displayed in my program guide are 104/106/107. Channel 105 no longer appears in my guide.
