To give more detail on this, it seems like they are all A-level vocabulary words, although oddly not all of them. I can’t think of anything I could have done to change so many at once, so it feels like something caused them to flip from “self evaluate” to “manual input”.
Alternate theory: the amount of sentences for words has grown lately. Maybe they had sentences and then the sentences were removed, causing them to default to manual input from reading comprehension? Just hypothesizing.
Did anything like this change in the last five days or so?
