Attempts can appear twice in the TDR or QSR if the course has multiple assignment sources. For example, if a course is assigned manually to a user, and then re-assigned via a rule, the TDR will show two rows, one with the assignee’s name as the assignment source and another with the rule name as the assignment source. If you come across an example of a duplicate, click the Field Chooser button above the results section, and click and drag the Rule Name column (from the column chooser box) into the rest of the columns to reveal the source of the assignment.
