Forced action happens twice if user is enemy

[Mistress Nebula]

I'm using YEP_BuffsStatesCore to force an action at the end of a state. It works great, AS LONG as the user of that attack is an actor. if an enemy uses the attack, the action happens twice and i have no idea what is going on.
this is the state's notetag:

<State Motion: Guard>

<Custom Leave Effect>
var skill = 104;
var target = -2;
BattleManager.queueForceAction(user, skill, target);
</Custom Leave Effect>

and this is skill 104's notetag. i honestly don't know if it has a chance to matter anymore:

<setup action>    
immortal: targets, true
display action
wait: 40
clear battle log
hide battle hud
zoom: 200%
camera focus: user
wait for camera
MOVE user: target, FRONT, 10
</setup action>
<whole action>
</whole action>

<finish action>
immortal: targets, false
MOVE user: HOME, 20
FACE user: forward
clear battle log
reset zoom
reset camera
show battle hud
</finish action>
