AAxis definition in FMGSServer.iocp.ini does not create axis in FMGS config tool

Hi Jeehell fellows,

I'm currently building my own A320 hardware on Arduino basis with SIOC/IOCP compatible output. - This part works pretty fine so far.
Unfortunately, I've noticed, that my AAxis1 does not show up in the FMGS config tool. :(
To be honest, I don't use the SIOC creator, instead I manipulate the ini and my SIOC script on my own.

Maybe anybody has an idea what I'm doing wrong?

Thanks in advance and best regards
Pate
