Problem with choose variation product from add_to_cart popup

I have recently purchased a CAIO license key and have come across the following issues:

On mobile, the Sticky Add_to_cart section does not display the product title and product price.
Clicking the Sticky Add_to_cart button triggers a popup with variation products, but selecting a variation (image label) does not work. However, if the variant displays as ‘Choose,’ it functions correctly.
