Okay! As expected, the issue is in these characters' Stats tags; there is a custom lighting attribute that should be blank, but the game seems to be interpreting it as a number somewhere and setting it to 0. Until I figure out the cause, you can fix this manually by deleting the 0 after Sparks||Small||32||16|| in each character's data:
From this...
<Stats>Emma/Strider||Fencer_F||Emma Strider||Human||Female||Champion||land||Sparks||Small||32||16||0||Sword||None||Motivate||Sprint||Shove||Pull||Motivate||Feint||Double Strike||||||97||46||5||4||51||27||5||1||0||20||65||50||0||0||0||0||0||0||100||39||90||false||Promoted,19</Stats>
...to this.
