OK, I found what went wrong. When I changed the main scope to the guide scope, I had changed the focal length as well, at least I thought it was changed. When I tested again the other night I realized that it actually did not change. Apparently you need to hit the "Return" key on the iPad for it to take hold. I have run into this on a few other screens as well. So keep this in mind when changing values. Go back to the screen and see if it really did change it.
