Yeah after doing some digging online I found the issue, Notepad++ is a very comprehensive editor and recognizes all the possible formatting codes.
Other programs including standard windows notepad are more generalized and not as comprehensive and so some of the more esoteric codes used to represent things like spaces are not always recognized, for example windows notepad is written to the windows standard for text editing and many unix OSX and mac standards aren't even recognized by it.
So basically the GC3editor that is mentioned in the xml files must use a spacing that windows notepad doesn't recognize but Notepad++ does.
Ultimately you are totally correct that typo still exists and now that they fixed the internal name for countermeasures the upgrade precursor for dronesentysystems doesnt work.
