Edit the app version in the app file

When I log into my Connect IQ account, go to the developer dashboard, select the app in question, I see that the app version is not correct.  During the process of updating my IQ app, I accidentally stated the app version as 1.2.72 instead of 1.2.70.  See the image below.

The version shows 1.2.72 and it should be 1.2.70.  How can I correct my mistake?
