Project admin can't close sprint

[Tim Saunders]

We have a sprint that encompasses 3 projects. All 3 projects require Project Admin permissions to manage sprints. I have a single user who belongs to the Project Admin role in all 3 projects but cannot close the sprint; he's receiving a "you need the Manage Sprints permission in all projects..." error. I've looked at the sprint definition and filters but can't figure this out. Any ideas how we could still be running into this problem or where to look for projects that may be involved but which I can't see?

Make sure all 3 projects are configured to use a permission scheme that allows the Project Admin to manage Sprints.

Two of them use the same scheme that give the permission to project admins, and that user is assigned to the project admin role (by name). The third project uses a slightly different scheme that also grants Maintain Sprint permissions to the project admins, but the user is assigned to a group that is assigned to the project role.
