Strange behavior with Helios

I'm attmpting to build my monitor config file for the saved games folder from a file that already exists that i got from a buddy. When i change the Viewports resolution and aspect, it makes the monitor setting file no longer appear in the dropdown menu of DCS under "Monitor"

Changing the name of the file doesn't break it, but changing the name of the setup, within the file, as well as changing any of the numbers in the file makes it so it doesn't appear any more. I even changed it and then changed it back and it stops appearing. Any thoughts?

When i change these values to mirror my setup, it breaks the file and it's no longer visible as a monitor option in the DCS settings.

Here's the fields that i'm editing, although, if i change anything in the file, even if i change it right back it breaks it and makes it so DCS doesn't recognize it any more.
