Sale Log Export

Hiya,
We are looking for a way to report on coupons codes that are being used. Meaning we would like to see which are being used the most, the least, ect. I can see the code on individual orders when I click on them in the sales log. However when I export the sales log say for the month of May that information does not pull in. Is this possible to make happen? Are we missing a step that we can set up to make this happen?

P.S. yes I know we are on a dated WP version, no need to tell me to update as I am aware.
