Does not add a variable woocommerce product to the cart. Error "Invalid value placed"

Faced with such a problem. Creating an online store on woocommerce. I'm trying to create a variable product using pre-created attributes. Variations are created and displayed on the product page. But when trying to add an item to the cart, it writes the error "Invalid 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 located on the product creation page first. If you move it if the other variation takes the place of the first one, then it will already be added to the basket, and the others will not.

Thanks)
