Cleaned atributes after add next language to existed product

I have installed Polylang and Polylang for WC . I had website in two languages and created all store with products in that two languages. Everything works correctly.
Next I set up next language, and after added “+” of version of product in new language, new version had cleaned all attributes , variants, and prices. I have saved it and unfortunately it looks like all attributes and prices was cleaned in all languages.
Have you any similar problems and someone found any solutions
