Doesn't add woocommerce variable product to cart. Error "Incorrect value placed"?

Question

Online shopping

Hello, I've run into this problem. I am building an online store with woocommerce. I'm trying to create a variable product using pre-created attributes. Variations are created and displayed on the product page. But when I try to add a product to the cart, I get the error "Incorrect value placed"? How can I fix it?

An interesting feature is that out of 3 variations, it adds 1 variation to the cart, the one that is the very first one on the product creation page. If you move another variation to the place of the first one, then it will already be added to the basket, and the rest will not.

Thank you)

Hello, faced the same problem. Renaming the slug of product attributes into English helped.
Maybe just updating them would help too.
