According to the author of the BP WC Vendors plugin(https://themekraft.com/), the form in my image above is your default WC Vendor pro form.
In the backend I have virtual/downloadable selected(see image):

And I also have virtual/downloadable product selected on the Product Form(see image):

Why can’t I then upload virtual products?
Kind Regards
