Copy paste rectangular grid Map Window but turns up blank. … .vmod?dl=0

I copy and paste the Custom map window but the copied window turns up blank, do you know why?

Or any map window for that matter. When copy and paste any map window, it will turn up blank. What’s wrong with this module?

Also when you rename any Map Window and save, it will turn up empty. I think it has something to do with the mod was built on a Mac while I’m editing it in Windows.

Found the solution. I just have to open Main Boards, Select Default Board Setup, click OK.
