Parking brake icon bug

Hello, I have had this issue for a pretty long time, but I didn't really care, because it didn't affect gameplay.
So i use a custom-made handbrake that uses some of the axis, not all, and the problem is that after I pull it and release it, the light on the "Tacho2" app is still on, but on the "Dashboard Indicators" app it's off. Also, when using a button, it functions correctly.

Another thing, with the Sunburst, if you lift up it's rear, on the damage app it shows up as damaged, any reason for that?

 

Yes it is registering 0%, you can see in the first picture, also sorry for being late.
