When you search Roku for this, it comes up as free on the Roku channel but if you click through I think it’s an entirely different documentary (a British-narrated cheaper doc), although it’s listed with the episode titles of the Ken burns doc.
Roku seems to be having major problems with the program description data base for The Roku Channel. They are aware of this and are supposed to be working on the problem.
Meanwhile, all you can do is bring specific errors to their attention by posting here as you have done.
Paging Roku employees @RokuAustin, @RokuERey, and any other moderators for follow up.
