TCA Spoiler Axis

[Bosseye]

Hi.

I have a modified TCA with a lifting spoiler arm lever. However if I move the spoiler arm along the axis it no longer works, and it appears the spoiler axis doesn't return to 0 in the aircraft (visually and within spad.nxt it does). The ECAM message still says the speedbrake is deployed. Is there any way of calibrating the spoiler axis? 

As I use spad.nxt the Microsoft controller profile is completely blank and everything is handled by spad.nxt

The spoiler arm button is wired to the eng fire button but for it to be recognised by the sim the axis needs to be in the speedbrake off position
