Brush Settings not updating XYZ dimension values

I’m new to UE4 but have experience in the past with Valve Hammer Editor. I’m using a Geometry > Box for floors and walls to design a simple level for learning. I’m using Geometry Editing to drag and adjust the X Y Z portions of my “box” to make the shapes I want, but the brush settings continues to give me the default “200.0” for the X Y and Z dimensions. It is not updating with the new dimension values I have transformed the box into…

It is mandatory for me to drag shapes to proper dimensions and know the values for shaping the rest of the room or parts of the map (hallways, corners, turns, etc). Please help!
