Panel Builder 800 v6 simulation

Hi,

I am having trouble with Panel Builder simulation. The window that opens when I start simulation is the same as the size of the panel, but the image and buttons and everything else is bigger so the entire content of the screen is not visible.
Please find attached example of the editable image and the same after starting the simulation. I used one from Demo project.
I also attached build output messages, log.txt file.

Do you have any idea how to fix the simulation?

thanks in advance,
Lucija
