How can I prevent Shopify from applying (double) discounts to my bundle products?

This is outside the control of the app itself and would be related to the broader Shopify platform:

Bundle Builder works with Shopify's discount codes so you can apply these on top of your bundles. If you don't want to include bundles with your discount codes, you can exclude the bundle products in the Shopify admin discount settings area.
