The worst bug ever seen:

Using data reports again, I have created a nice report that works well. But if I try to add to it a new group header and footer like MSDN says, then it fires saying that: "Report sections do not match data source." Why??? Any explanation?
Keep in mind, that when I set the datasource and datamember properties of the report, I select then "retrieve structure" in order to modify the report having the suitable sections according to the data environment. That works well, but why I cannot add one more grouping information? (I have already one)....
