In Wizards, the username menu contains duplicate entries for users who are in multiple groups. I think this problem is a regression that was introduced in the April 2 release. To replicate,
1. Create a portfolio site with two groups.
2. Add the coordinator to both groups.
3. Add unique members to each group and add one or two users to both groups.
4. Create or import a wizard into the wizards tool and publish it.
5. Examine the dropdown menu. Users that are in both groups show up twice.
