The lesson caption shows the US keyboard irrespective of keyboard selected. Hence where lessons cover the keyboard keys at variance to the US keyboard, the caption becomes confusing to the user. However the exercises reflect the Keyboard requested.
Since I am using a US keyboard, I’m afraid I haven’t run into the issue you’re describing here, but it certainly sounds frustrating! I would be interested to know if this is a bug or a programming flaw. Might be worth getting in touch with support as I could see this becoming more and more frustrating as time goes on.
