Cart Strangeness

Hiya!

I've paid for, downloaded, got my keys, installed, and am running Object Desktop with zero problems, One odd issue is that it's still in my cart, it's not a big deal  but it just kinda bugs me that I cant remove it, the "-" is grayed out, I can add more with the "+" button then use "-" to go back to one, but I can't actually remove it as there's no delete button, I closed and reopened Chrome, I've logged out from Stardock and back in, and I've restarted my computer too, but nope...it's still there

I know it's probably  something embarrassingly simple I'm missing, but as Homer says...it's my first day! :/
