Sorting field under EDD/BAQ

Hello epigurus,

We would like to see accuracy of our company shipments month wise. Idea behind this is if ship date >current ship date it will show early, if same then on-time and if smaller then it will show late. Now, our shipping department only wants to see late statistics for all months. I did created a BAQ(works fine as expected) and also a dashboard.

The problem is after creating statistics in dashboard it shows month value wise not month name wise. I might be missing something about how to sort them in order of Jan, Feb, March and so on. Right now it shows like this

Any help would be appreciated!!

Thank you for your time.
