Why is xml Design in Android S not displayed correctly?

Question

android studio

Please tell me why in the preview of the design of the xml file in AS it is not displayed correctly, in the preview I chose the same device with the same resolution and screen size as in AVD, while on the virtual machine my elements climb out of the screen and overlap each other friend and in the preview everything is exactly as it should be? On my phone with the same screen as in avd, I also have elements falling out, is it possible to correct this somehow, well, or understand how to work with it, thanks
