Wrap renders an object which exited the layout, on its opposite side. And that is exactly what is happening in your game. You reach, for example, the right-most of your layer and then your ship gets "teleported" to the left again.
Also "Scroll To" doesn't bug out, it's also working as intended. There's simply nothing for it to show you, on the right or left-most edge, because that's where your layout ends and there's nothing beyond that.
Remember that when you cross the edge, Wrap puts you on the opposite side of the layout again. That's why the enemies don't appear before crossing the treshhold - because they're not there.
So everything is working as intended.,
It does not wrap an entire layout on itself into an infinite loop, like you're trying to do.
Also i remember reading Wrap shouldn't be used on Physics objects. It bugs out because of the way the Physics engine itself works.
