I am facing the same issue, but only with Api Lvl 17.
Try selecting a different Target.
Question
This is a screenshot to illustrate what is happening
As you see in the image, everything is shown to the right, even if I change the gravity field to "center". The thing is that when I test it on my phone it is shown as it should. But it is tough to be always running the app to design it.
Does anybody know the reason? Thank you very much!
