I am trying to remove the test responses from my standard report but absolutely nothing shows up in the sidebar to the left where the filtering option should be. ???
Are you on the SurveyGizmo Free Plan? I ask because filtering is not available on the Free Plan so that might explain what you are seeing:
If you are on the Free Plan, you may need to delete the dest responses from Results > Individual Responses so that they don’t show up in the report.
Hope this helps!
