Product Images not changing when variation selected

running Shop Studio Theme, WP 4.9.4, WooCommerce

after updating to WOOCommerce 3.3.2, when selecting a variation of a product, the image changes in the image gallery, but not on the selected product image. So, it would appear to be a minor fix, as it does change the image, just not in the correct location.

The only debug error I see, is a missing bootstrap file https://www.insani-ts.com/wp-content/themes/shopstudio/css/bootstrap.min.css.map
