sales pipeline report for opportunities - data is presented wrong in display

sales pipeline report for opportunities - data is presented wrong in display

My issue is that sales pipelines should show the strongest / highest % at the bottom of the funnel and the lower probability at the top.

The hierarchy should be:

10%
20%
30% 
90% etc

It displays as

90
30
20
10

How do I get it to reverse the the order?
