You're not using Anim Battlers. That's evident in that the 'enemy' battlers are default-styled (you move 'em around in the troops section the way you want). Now, those Battlers of yours.
Huh? Looks like you took a characterset image and erased all but the top center image leaving only a smaller battler to show!?! You don't get this with the default actor battlers, do you?
I mean, RTAB by itself doesn't change the position of enemy battlers, let alone change the size of actor battlers. It retains the 'Front View' perspective of the default battle system, and adds a camera zoom feature (which I like to turn off when I use anim. battlers).
You using anything else?
