Checbox Conflict

Hi,

I need to resolve some plugin conflict. I’ve added custom checkbox that needs to be required before add to cart.

And if I set checkbox as required, there is a small conflict. CPO is not calculating price after checked checkbox.

Also after updating CPO values (adding more persons for example in calculations) display price is correct.

The problem exist only if mark checkbox (when required) but not changing default input values. After changing values, price is calculating right way.

See:https://wakacyjnepomysly.pl/produkt/rejs-statkiem-do-parku-krka-z-lunchem/

If checkbox is not required everything is working fine.

Also checkbox is working perfectly with product that are not using CPO.

Do you know some workaround?
