Strange issue with orders, if the last item in stock is sold.

[MrTouch]

Hi, I have a really strange issue and i dont know where to start looking for a solution.

 

So this behavior started yesterday. We did not change or update anything. But somehow prestashop started by creating orders with a strange (not the normal id which i configured in the beginning but one with letters instead of a number - see screenshot 1). This only happens, if the customer buys the last item(s) on stock of a specific product.

In the order itself there are no items listed. (see screenshot 2) so i dont see which product the user ordered. (I have to go into the user and check his cart to see what his last cart was, which is not so conviencing.)

I really don't know where to look for this issue. i dont know how i can find out which module causes this problem, maybe it's some kind of missconfiguration of products.

I hope someone can give me a hint where to start looking deeper into the problem to find a solution for this.

My Prestashop version is: 1.7.6.2
