- Summary:
Group does not work correctly [0001]

- Bugzilla Bug (s) Resolved:
183947

- Description:
The data _expression_ of base series was omitted when the data and aggregation _expression_ are both duplicate with orthogonal series, so the group data was wrong.
Now manage to tell the difference of them to avoid wrong grouping.
