Hello, i am currently learning japanese and everything works great so far. I tried importing a custom lesson and realized that the subtitles are romaji. I accidentally swiped right and marked every word as known. I got to many coins for this so i deleted the lesson and wanted to unmark the words. This was not possible anymore. I had to import the lesson again to unmark the words. The known words for the day are back to normal but i still have a lot more coins then i should have.
