The Exclusions Report displays all of the reasons for exclusion for each Level, Form, and individual exclusion answers. The values displayed will depend on what is set as your Agreement Level in the Level Settings and your focus should be on that respective section in this report. For example, if it is set to "Answer", you will see the total number of references where an "exclude" type answer was selected. If you change your Agreement Level, make sure to reconcile your references so the change is reflected in your Exclusions Report.
