Batch create users to existing sites in a multisite environment

I have tried to use the batch create plugin in order to add users to site in a multisite environment. I am logged in as a superadmin and then I go to the admin panel for a specfic site. I than choose batch create under superadmin. The import goes great but the problem is that the user ends up without a connection to a site/blog. I only see the user under superadmin. The user does not get any user role either.

How should I proceed?
