Hey @jamespratt yeah you seem 100% right … I personally didn’t make the distinction between what I marked as “known” and what you refer to as “read”. Unfortunately what I’m doing now is marking all of my known words as level 4, just so that I can export them. Quite a disappointing experience, just having started out.
EDIT: Now thinking about it, I guess the better approach would be to mark all my known words manually to “known” so that they show up in the export. Sad that the “auto” marking of words as “known” skips this
