It is not obvious just by looking at the Value's content, but there are 2 whitespaces in between powershell.exe and -NoProfile.
After copying-and-pasting it into the box that requires it (i.e. it is added as a "custom option"), I saved it. Copying-and-pasting the content in Value that was now reflected back to me showed that there was only 1 whitespace.
There appears to be no other way for me at the moment to use another field or piece of content for this exception, and thus I would have to look at resolving this error/bug(?)
I think the problem we have is that by default HTML/DOM displays multiple spaces as a single space and that we are doing it as well. We really shouldn't allow the HTML/DOM to change your value when displaying it back to you. We will want to fix the display issue.
