Description: The result of grouping is wrong. Step to reproduce: Steps to reproduce: 1. New a report. 2. Create a data source and a data set based on the report. 3. Drag the dataset to the layout, and set two groups on the table. The first level group information: Group key: CITY Interval type: prefix Range: 1 The second level group information: Group key: CUSTOMERNUMBER Interval type: Interval Range: 4 4. Save and preview. (Please refer to the attached design file) Actual result: The result of grouping is wrong. Expected result: In the second level group, the CUSTOMERNUMBER 157, 303, 357, 323 shouldnt in a group. They must be regard as single group according to the conditional of the second level group.
