I have not been able to recreate this. Are you using the most up to date version of Tableau Server?
I believe we are on 7.0. After I publish a dashboard, and its sent out to our users with interactor licenses, if they hover over a data part they see an exclude/include button. I wasn't quite sure how that functionality works or how to enable/disable it. Maybe it was associated with a filter we put in the dashboard? Thanks for looking into this.
