Report

As for any other product available in the shop, the sales related to the product “Bundle” are registered within WooCommerce report.

By default, only the product bundles are displayed in the report, whereas the products associated to the bundle are left out.
This behavior can be changed by enabling the “Show bundled items in Reports” option that you find in the plugin settings dashboard.

Now, also the products included in the bundle are shown in the report, in the amount of zero, as you can see in the image below.
