We're still working to get the initial settings just right, so I really appreciate the response!
So, first, the vocab. By default, the site shows unknown kanji in grey with furigana on top of it. You can change this to not show the kanji at all but hiragana by going into Settings > Vocabulary > Shown unknown kanji like this
The beginner level assumes a small amount of kanji knowledge. However, you can quickly toggle off anything you don't know at the moment and wait until you study it in the site to have it appear! I'm working on a new version of this page that'll better help users like you, but for the time being, please do this:
Learn > Kanji Index. Here, you can select, for example, Proficiency Test > JLPT > N5. The lowest level is based off of this. You can see a lot with the light bulbs indicating you know them. you can quickly turn them off one-by-one, or turn off the entire page. This will prevent them from appearing as kanji without furigana.
If, after this, you are still having issues with "black" (known) kanji, I'd love to see if there is a bug affecting your account. You can either post screenshots to this thread, or (probably easier), use the "problem?" button that appears at the top of the site when you are quizzing. That'll send me a direct copy of your quiz so I can see exactly what you're seeing!
Please let me know if there is anything else I can do to help! I think you've also helped identify that some users have some vocabulary and grammar, but still feel relatively weaker on kanji, so the site should be able to better help users like that. I'll keep this in mind as I update the site!
