Why does "Salaried" show up on the timesheet?
This is an option that may be controlled in via the property "Show Classification on Timesheet Preview" as in the screenshot below. When the property is set to true, the salaried status from the Person Profile will display. When the property is set to false, the salaried status will not display.
Navigate: Admin > Properties > Edit Settings.
Navigate: People > List > List > Edit Clock Icon > +Timesheet.
