Solving playback issues

[NanFit127]

This is the weirdest thing. I tried to start watching The Marvelous Mrs. Maisel, season 4 tonight on my Roku (Prime Video) and it was in GERMAN!! I checked the language selected on both Prime and the Roku -- says English in both places. Here's what's even weirder: I can watch that show on my laptop -- through Prime, of course -- and it's in English. AND every other Prime show using my Roku is also in English. So the ONLY show that's in German (??) is The Marv. Mrs. Maisel (all seasons even!) on my ROKU. 

Anyone out there have any ideas of how I can fix this? (btw, I've signed out of Prime, then signed in again, etc).

Wrong language or verbal description of action on screen when watching program.
Some programs contain multiple audio tracks that can be selected, such as different languages or verbal action descriptions for the visually impaired.

The Roku default method of accessing your choice of audio track is to press the * key on your Roku remote while viewing the program and examining the options presented.

But more and more channels are not using the Roku default but substituting their own method of access -- I'm guessing this is so they will have consistent controls with versions of their app running on platforms other than Roku. Often these options are accessed by pressing the up and/or down cursor control keys while viewing the program to pop the channel's own control options on the screen.

[Edited to add..]  On my Prime Video, audio track is accessed from within the program via UP twice, RIGHT twice.
