I think this may be a possible bug with the Repeat group header on each page setting in the Group Expert dialog.

I found that if the group starts a page on its own and is the first thing that is displayed on the new page, then the group is actually duplicated. By "on its own" I mean the report engine decides to start a new page because the next group cannot be fitted on to the same page anymore. No "new page after this group" or anything turned on.

Has anyone seen this behaviour and can advice on a workaround?
