[Scripting Question] Elite Battle System EXP Error

I am trying to use the default Essentials UI with EBS, which has the ID of '0' in the Settings script section. I am using Essentials 17.2, and an unmodified EBS.
At the end of the battle, it seems the EXP bar glitches out:

---------------------------
Pokemon Essentials
---------------------------
[Pokémon Essentials version 17.2]

Exception: NameError

Message: uninitialized constant PokeBattle_SceneConstants::EXPGAUGESIZE

PokeBattle_Battle:1773:in `each'

PokeBattle_Battle:1773:in `pbGainEXP'

PokeBattle_Battler:3255:in `pbUseMove_ebs'




Then, when I finally end the battle, I get this message. The game then crashes.

Any help would be appreciated.
