XML Publisher Report using dynamic columns displays incorrectly

Hi,

An XML Publisher report based on Oracle Reports and that is using dynamic columns on the rtf template is displaying the output incorrectly. If employee A has done trainings Z1, Z2, Z3 and employee B has done trainings Z1 and Z3 for example, the output is displaying incorrectly like below:

                    Training          Training     Training

Employee        Z1                  Z2               Z3

A                  01/01/2015   10/02/105    20/03/2015

B                  01/01/2016    20/03/2016    

But when you check the record in Oracle EBS Self Service, you can see that employee B did not do the training Z2, but instead, employee B did the training Z3. This means data is being pushed left is the corresponding record is not there.
