Removeing Development Build Text In A Project

Hi Everyone,
I would like you to notice that generated build has ‘Development Build’ text appears always Even though we are not implicitly selected at Unity Build Settings.
Can Anyone Please Tell Me How To Remove That Text From My Project?
I Am Using Unity Version 5.5.0f3.
Please Give Me The Urgent Rectification For That?

If it’s definitely unchecked, try cheking it again and unchecking.
