I had the same problem on the previous version, but this new version has fixed the bug on my Fire TV. Perhaps this workaround that I posted in the other thread will work on the Shield if it’s still a problem on that device.
I found a way around the GUI to get to the Recording Options of the cancelled show. I navigate to the About and select it, then I cursor to the right to highlight the text, and then I can navigate UP and select the Recording Options to then set it to None which removes the shows ICON.
