Select Version to Test is empty in Internal Testing iTunes?

I have uploaded my App succesfully to the iTunes. Now i need to test the app using TestFlight. So i added some Internal Testers. But when i clicked on Select Version to Test The latest builds are not showing up in the list. I don't know why?.

I also verified my Build 11 on the iTunes. It shows that there are no testers available for this build.

How can i add Testers to Build 11 ?
