Membership Plugin

Have installed membership plugin on wordpress multisite, looking for people to create their own website, have used membership to pay for annual membership, all works fine except after they have paid and created their own site, they then have access to main website dashboard as well as their own, am looking for them just to have permission to access their own website not view the main website. When the user is created in back end they get permission to view both, have i missed a setting?
