Thumbnails moved to bottom of screen

I have two TVs running TabloTV on Roku Ultra’s. One is runnng fine as it always has. The other has had a change I cannot understand. On the second TV when I am using the Tablo app playing back a recording the thumbnails have dropped to the very bottom of the screen. It can still be used, but it is odd and different than it has been. Has anyone else seen this? Is there a fix?

Are both Ultras running the same version of software?

When my Roku Ultra updated to software version 10.5.0 build 4201-46, the thumbnails dropped to the bottom of the screen. Since the Tablo app (version 2.18.0) was the same before and after the Roku update, I surmised that the Roku update was responsible for the change.

I think you are right. The one with the problem is running the 10.5.0. The other is still running 10.0.0. For some reason I cannot even make the second Roku update. It keeps saying I am up to date.
