Waterfall: revert category order

Hello,

I have recently started on a PowerBI course, and as part of the tutorial we have to create a waterfall visual. Is there a way to revert the order of the categories though? it works fine on all other visuals, only at Waterfall it is showing the years in a reverse order (back to the future?).

if you know how to fix this, could you please show it to me with pictures?
