Members of a group I (site administrator) created cannot edit their group's space overview?

I am using groups to organize ~150 users into groups based on "teams." There are spaces created for each team, and in the space permissions, I've designated that only members of the team and site administrators have full access. However, with only one specific team, members of the group cannot edit the overview page. They can, however, edit pages and site permissions. Why won't Confluence allow these group members to edit their space overview?

Did you restrict editing on that overview page?
