WBS Product Bundle – Digital and virtual

How to set ‘WBS Product Bundle’ as Digital and virtual?

I have set my checkout to a simplified field for virtual and digital products.

When I add any digital and virtual products, my checkout will not ask for any shipping and billing address.

With WBS Product Bundle category – I have added 4 products that are both digital and virtual, but at checkout, it still asks for shipping and billing information as if it’s a physical product, I want to skip that.

How do I go about that? Thanks
