Are the Design Checker sheet format paths case sensitive?

I'm trying to set up a Design Checker file to verify that all drawings are using one of a set of sheet formats.  However, every document fails the check, and I've noticed that the only difference between the path that shows up when I use the Learn Checks Wizard is that that path is lowercase, whereas when I use the 'Add' button to put in all the other possibly valid templates is that when I manually add the paths, they include capitalization.  Has anyone had a similar issue, and if not, why aren't my documents passing the checks, when I know I have the same template loaded that I've specified in my Design Checker file?
