Development Build showing despite not being selected

Not sure what’s going on here. But I’ve created a simple game for Windows Phone 8. In my build settings “Development Build” is definitely not checked, yet when I build my app on my phone it shows “Development Build”.

It’s probably something really simple, but I can’t figure out how to disable this.

Any ideas?

Thanks

Turns out that even when you deploy to a phone in “debug” or “release” mode via Visual Studio it still shows the “development build” message. You need to build it as “master” in VS for it not to show
