add to cart minus button not showing and active

Hello,

I just moved from replete to enfold.
1) In a product detail page of an variable product I can see the +button but not the minus button.
when I inspect the page with firefox, I see it is there, but exactly on the same position as the plus button.

In the rules console I see this:
wc-quantity-increment.css:39

    .woocommerce .quantity .minus, .woocommerce-page .quantity .minus {
      bottom: 0;
      right: 0;
      border-radius: 0 0 2px 2px; }

When I deactivate right: 0; from the class, then the minus button moves between the quantity input and the plus input.
But it should go like minus button | qnty input | plus button

2) in replete the quantity and add to cart button for a variable product was only visible when the customer selected the variation. In enfold it is visible before the customer did any selection.

Thank you for help
Tom
