I'm not 100% sure this is a bug or it's just me just misremembering things but I've noticed an abnormal amount of vocab terms to review in older schedules (I haven't inactivated them yet). Usually I wait for at least 40 terms to review but this week I've been getting 60+. I just did a run of the "Words for Beginner Japanese" and I hid more than half of the terms, since they've reached 100% proficiency. I'm almost certain that I've already hidden them, but this all could be a coincidence. Is there a way to check whether my previously hidden terms have been unhidden?
