What did you set the values to? One way to check to see if the rules are in use is to log in to your server and use the #rules command and look for:
RULE_INT ( Combat, HitCapPre20, 40)
RULE_INT ( Combat, HitCapPre10, 20)
Note the values on the far right are the damage caps, so theoretically you could modify those to whatever
