The hroot_in and hroot_out are root of hiearchy tree of hist entry. But as hist entry is initialized by copying existing template entry, it sometimes has non-empty tree and copied it incorrectly. This is a problem especially when event group is used since it creates dummy entries from already-processed entries in other event members.
