Products stopped sorting alphabetically

Site URL: https://www.middleburgtack.com/jumping

Greetings all, when adding products through Commerce > Inventory > Add Product, they previously sorted alphabetically by product title automatically. Just recently, for reasons I can't figure out, they've stopped doing so automatically; any new product added just goes to the bottom of the list. Any ideas why that would have happened? I can't think of anything I've changed that would have caused that, and apologies in advance for probably missing something very stupid. Thanks all!
