I am on 2.2.8, and it displays this on both my Tablet using the Android app, and the Chromium web browser on my laptop running Linux. I also tried it on my wife’s Windows-7 laptop with Chrome. Every one of these combinations showed the Bogus recordings.
I have seen this issue twice on previous versions of Tablo software but not yet on 2.2.8. The first time was in the web app and a disconnect and new connection resolved the issue. The second time was observed in the Roku Tablo channel and a manual guide update resolved it for me.
One thing I found when I was having that issue prior to 2.2.8, is that when a new program for those thumbnails was recorded, I appeared under the problem thumbnail, and when I deleted the program after watching, the thumbnail then disappeared. Alternatively, the Tablo support folks can delete the thumbnail for you if you file a support ticket with them.
Odd… I just picked up one of these as well with 2.2.8, tho interestingly enough, I see the program-less thumbnail on the chrome web browser, but not on any of my Rokus. The thumbnail is for the show “Beyond the Tank” which had broadcast a rerun last week, and I have that show configured to record only new episodes. It showed up the day following that broadcast. I’m not overly concerned about it, as one way or another, it will soon be gone.
