Conflicts with WooCommerce Product Bundles plugin

We recently purchased “Boost Sales for WooCommerce”, and are having problems in the cart when using it with bundles provided by the plugin “WooCommerce Product Bundles” (https://woocommerce.com/products/product-bundles/).

When a bundle is added to the cart, Boost Sales seems to be affecting cart calculations:

1) The bundle components are not adding to the cart total at all.
2) The components are subtracting from the number of items in the cart instead of adding to them.

For example: http://propmd.cloudaccess.host/product/qs-e-j-4-3-4-bundle-1991-newer/

If you add, say, one of each item on that page to the cart and then view the cart, you’ll see the total is $0 and the carts says it has -2 items in it. This behavior disappears when “Boost Sales” is disabled.

Please advise… we’re hoping to push this site live very soon.
