Sexout Spunk's pHUD Arousal Meter

[Poetic Motion]

I installed Sexout Spunk, and pHUD support 2.2.

 

Lust Tracking is working well. (Figure is apeared at the HUD from 0 to 100)

 

But Arousal meter is I think not working well. (Figure is not appeared, just a blank, as the screenshot attached)

 

I want to ask how I make it works well.
