Analysis report for course completion of specific course

We are a new Oracle customer and so new to creating Analysis criteria and want to create a report that shows the course completion status of a particular course. We have selected the following columns in image below which results in a list of all employees and courses as well as their status of completed. When we filter by a particular course, that appeared in the results when no filter is applied, an error appears. (see image)

Has anyone created this type of report whereby we could filter by a particular course.

We are using Version 24A and are Redwood enabled
