missing class

Hello,
I’m sorry to write here, but I can not find a technical section anywhere.
I would like to advise, we have eshop https://www.nadrznavodu.cz/e-shop/plastova-jimka-clear-1000l/ which uses in woocommerce new (individual) posts type “Vyhody (in English Advantages)”. In woocommerce version 3.3.5. my product lists the “vyhody(Advantages)” as individual classes for product, and I was able to put the “badges” above the button to the basket. The new version of woo (from 3.4.0) does not this classes, could you help me out of this situation out? Do you not even plan to post custom post types in the future? Look at screen https://drive.google.com/file/d/1NG2ceyUTwGq33NvSu_OtihzrqGDwMiBL/view?usp=sharing.

Thanks.
