Stock number is saying 2 is being checcked out at a time

This plugin was working fine (i thought). But when I add 1 item to my cart, the displayed ‘stock’ number goes down by 2. When i then proceed to check out, it again says only 1 item is in my cart (which is correct). To make things even more interesting, the stock number displayed under my item’s picture works perfectly, but the one in my sidebar “add to cart section” it is doing this.

I have deactivated every plugin, but nothing works. I tried another cart stock reducing plugin and it worked fine as well. Although it doesn’t have the awesome countdown feature yours has.

I hope you can provide some insight here.
