Not working with WC 3.8.0

Hi

This is not working with WooCommerce 3.8.0 and StoreFront at all.
Well, it’s only working somewhat.

When setting a default variation, it ignores the actual variation’s price and shows the lowest price of all the variations.

When selecting a variation, the price will not update unless you click somewhere else on the page or select a new variation.

Any help or update to these problems would be greatly appreciated.
