Woocommerce Order with products variations

Hello,

I have an issue with products that contain variations in certain orders, not all orders. Sometimes I find the product without the variation in the order (volume, perfume), even though it’s not possible to add the base product to the cart and proceed with the order.

How it’s possible ? Thanks.

I tried to reproduce the command with the same products, and I didn’t encounter any issues, the variations were indeed present.
