Hello,
Add the below code to Theme Options > Custom CSS
@media only screen and (max-width: 480px){ .rtl .single-product-builder .et_product-block form.cart .quantity-wrapper:before { -webkit-transform: translateX(calc(100% + 10px)) translateY(-50%); transform: translateX(calc(100% + 10px)) translateY(-50%); } }
We’ll fix this in the next theme update.
Regards
