New to the game, just purchased yesterday, so bear with me.

Currently running version 1.3. No mods installed, .. just the offical addons.
I'm playing Scenario 2 of Gettysburg, i.e. McPherson's Ridge
When I use the up-arrow to go thru the Chain of Command, .. once I'm at the top level, .. I can no longer go back down. :huh:
Also, sometimes when I'm at the top level of the Chain of Command, whilst playing the Confederates, I end up with the correct flag and picture, .. but with George Meade's name and info (instead of Lee's). :ohmy:
So, what am i missing? Is this a bug?, or, is there something I'm supposed to fiddle or tweak?
Thanks and Regards
Tom
