Change image when positions gained/lost in iracing

Hi,

I'm trying to create a dashboard widget for iracing so it will display a green arrow up when I gain positions and a read arrow down when I lose positions. 

I have downloaded the @romainrob iracing extra properties

UPDATE:

I found

[IRacingExtraProperties.iRacing_Player_PositionGain]

 and added it to the visibility of the green arrow up and

[IRacingExtraProperties.iRacing_Player_PositionGain]<0

 for the red arrow down. For the red arrow down I get Raw result as true, but when I race I see both images at the same time. I can have +6 positions gained, but both the red arrow down and green arrow up are showing.
