Custom Press in Multi-Site Does not allow admin (not super, just admin) to create custom post types,

So I installed Custom Press on a wordpress multisite installation at

However, it doesn't allow the administrator role (not super admin, just admin) of a site or sub-site to create custom post type or fields or custom taxonomy, etc. Only option availbale to the site administrator is to export various custom press settings.

Can you help me out in understand how this can be enabled?
