HeistMeisters - Godot 3.1.x issue - NinePatchRect Margin crosses over with Size?

Hi,

HeistMeisters - Lesson 100

I followed the steps, but get different results.

Using Full rect on NinePatchRect2 actually shrinks the image form the correct size to too small.

Adjusting the Right and Bottom Margins actually resizes the image from full size to a tiny square.
