Thank you @Denys_B. I sent a reply in email, but realize now, that may never reach you. A copy of that below.
If I understood your post correctly, closing the last lesson on the web during the evening on Finnish, should result in the listening results for Finnish in the morning on Android being added to Finnish. As I only do Korean in the afternoon and on the web, they should not hurt each other, as long as I close the day in Finnish.
Thank you for the update. Could I receive an update when it is corrected, please? Then I can forget about always closing in Finnish, and just do what fits the day.
