Alright I'm assuming you've cleared out the default settings from the demo if not, do that.
If the problem still persists check you have the right number of frames and that that battler is aligned properly, the system allows from virtually any number of frames and poses so a battler from here may still not have the right amount of frames/poses and you may have to change the script to fix that (configuration section of the script) if there is still a problem after that then show me the battler.
