Stacked bar order on dashlet doesn't reflect report

Hi all,

      I have created a stacked bar chart showing each salesperson's Opportunities by Sales Stage (Customer Journey step). In the report view, it displays the values in order (Stage 01, then 02 etc). But when I add that report to a dashboard, it jumbles the order. It's only doing that on one of the two reports I created (one for this year and one for next) but I can't see what is different about them. Any ideas?
