autopilot altitude hold value

[windingdk]

Having problem fetching the autopilot altitude hold value. I have tried the following value: AUTOPILOT ALTITUDE LOCK VAR but is does not set a value on my 7 segment display. I have tested that the display works with the COM1 freq, so I know that data can flow to the display. The display always shows 00000000. I have the following setting. Any idea of what I am doing wrong?

I have also tried to fetch data through FSUIPC but still no luck. Can somebody try it out. I am using the Fenix A320 aircraft and Mobiflight v. 9.4.0
