Can't modify stats?

I didn't know where else to post this... I'm trying to modify the stats of an Elephant unit in Europa Barbarorum, but it won't let me. No matter what I change the Attack and Charge value to (yes, I'm confident that I'm changing the secondary attack values), it just resets to default and/or the changes won't take effect. What am I doing wrong?

EB uses .bat files to swap around SP and MP versions of the EDU, which are stored in another folder, right? Try editing these versions instead of the one in the data folder. Though you could also ask (actually search first) in the EB subforum.
