Updates to Underlying Data Not Showing

Updates to Underlying Data Not Showing

Hello Team,

When I add a column(s) to the underlying data of a chart it does not stay added when I reopen the chart. When I try to save after making the intended changes I receive the message "Already saved. No modification found". I tried adding fields and then making an adjustment to the chart and then saving, but the underlying data still doesn't maintain the changes.
