Gascuddy not showing mileage per tank

[nmcclumpha]

I am rumming ios 7.0 on iphone 5S and gascubby 2.7.4 and whenever I add a new fill-up entry it does not show my mileage for the previous tank. It shows the average on the bottom but not per tank mileage. i have used it for a couple years and it use to work like that but no longer does It is the version or something in the settings.
