WordPress Multi site: all pages and post said: Locked by Super Admin

Hi

I am a super admin of a WP-Mu site and I have added new administrators to my sites in my network. But they cant edit any posts or pages, when they log in and try to edit a post or page it said: Locked by Super Admin

If I then log in as super admin and go to edit user in network admin and tick the box: Grant this user super admin privileges for the Network, then it works. Then they can edit all posts and pages, but then I give them access to the network. And I don’t want to do that, they should only be admin and have access in there own site.

Please help me, I cant find any information about this anywhere,

Thanks in advance!
