I've heard this a lot lately:
I updated my group and reinstalled my policy, but the change to the group doesn't look like it was applied.(Note: See correction below. This doesn't apply to policies but only to reports)
Well, this could be a result of a recent change to how groups work in Guardium. The best thing about it is that reports that use a lot of group members are going to run faster (especially if the CM is far away from the unit running the report). The worst thing about it is that you need to know more about how things work in order to see your changes applied immediately.
