I don't really understand why this is the case, but for some reason it is not possible to add resources with asset studio without them being in this weird shape:

Am I missing the point, I cannot really see an intention in this, shouldn't you be able to add resources exactly as the developer designed them?
Additionally I would like to use googles stock clip art, however this wont allow it.
This is due to the new "Layout Rendering Engine" in Android Studio.
Disable using the following:
Settings->Experimental->Use new Layout Rendering Engine
