dropdown woocommerce menu

dropdown woocommerce menu to select quantity/ size (variations) is not showing at all on my website. https://www.compostablealternatives.com.au/shop/

I tried to desactivate my swatches plugin but same problem. I update my theme (astra) same problem, I desactivate woo and reactivate same problem. Dropdown menu or swatches are appearing very well when I am log in.

Can someone have the solution
