still seeing deleted image, album in account stats

I uploaded a picture, and put it in an album to make it public.  When it still had zero views and wasn't in the gallery the next day, I read the FAQs and discovered that apparently imgur is for sharing pictures that are already popular on the internet, which I don't fully understand the point of, but whatever's clever.  Because I don't actually want to spam the entire internet with a picture of my dog, I deleted it, but kept seeing my "popular album" with the thumbnail of that picture in my account stats.  So I deleted the album.  Yet it still appears in my account stats.  I can click on it to get a 404, but the fact that the album used to exist, and the thumbnail, is still showing up, which means the thumbnail is still being stored.
