Random Monster placement not working

Hey everyone! Having a problem with the random monster placement function. My monster spwan outside of the screen. I did go to the hub and paint a monster spawn area on my screen putting the right Demo Screen X and Demo Screen Y coordinates of my screen but it still doesn't work. What am I doing wrong?

In NESmaker 4.5? I don't think this feature still works with the recent versions...

I'm with version 4.5.6. So that feature doesn't work then. So placement of monsters can't be random then?

It's a feature from an older version... and sadly, that feature was not implemented in the modules that comes by default with the 4.5.6.
I don't say it's not possible... Someone will have to code that, in order to make it working
