The detail section of each data item is rendered as many times as the number of records in the corresponding data source. Hence, if the employee's information is duplicated, there should be two records containing this information, perhaps one with the College and one with the University.
The issue seems related to the data organization.
You may open a support ticket and send us a runnable report definition (i.e. containing sample data) so that we can investigate it and try to suggest a solution or workaround.
