Item in store not updating as sold

Using Website Builder. Item Elephant Stein Golden Russet $65 sold a couple of weeks ago. At first is did not register as sold, then it did. Then it showed back up as not sold.  So today I went to "manage store' and manually clicked "0 items" and toggled it to not be visible. It STILLS shows up on the website and lists as 1 item available. I have checked this on both a desktop and mobile.  www.foelberpottery.com

I am getting ready to upload a few multi-item workshops and merchandise and it will be a nightmare if there are glitches like this. Please help!
