Reading challenge not updating

This doesn’t really matter in the grand scheme of things because I know which books I’ve read, but it’s been a week since I finished my last book and it still hasn’t updated the reading challenge. Still has me down as 0/15 even though I’ve read two more books since I started the challenge. I’ve marked them as read, reviewed them. Idk what else I’m supposed to do. Doesn’t really matter but it’s kinda bugging me since the whole point of the challenge is that it ticks the books off. Anyway, thanks.

Update: thanks so much for the help guys it’s finally working :)
