Saitek panel/Autopilot commands problem

[mlb406]

Hi, I use a Saitek multi panel with my setup to control the autopilot, and I've just bought the C525 and have been having an issue with it. 

For some reason, I can't get the autopilot mode buttons to register when pressed on the multi panel. I use the Xsaitekpanels plugin and have tried remapping the buttons to both the standard XP sim/autopilot/ commands, as well as the afm/cj/cmd/autopilot/ commands, but the aircraft just doesn't seem to like it. The thing that makes it even weirder for me is that the aircraft reacts to these commands when I use either a keybind or the DatarefTool plugin. The latter plugin even registers that the command has been triggered by the multi panel, and there is a clicking noise for each button, but nothing happens on the actual aircraft. I have been able to map the heading/altitude/course knob(s) just fine, the flap switch works fine, and I have even been able to map the pitch trim wheel to the autopilot pitch wheel on the 525. I haven't experienced this at all with any other addon, and I was hoping that someone might be able to point me in the right direction for solving this issue?

Many thanks!

Ok so to add to this: I've used Datareftool some more and it appears that the commands only work when you press the "activate while held" option, not just "activate once". Seemingly the button press sent through the Xsaitekpanels plugin arrives as an "activate once" command, instead of the former, so it doesn't do anything but make a clicky sound. What makes it weirder for me is that I can remap the button to the afm/cj/autopilot/ datarefs instead, which then physically presses the button on the aircraft, but doesn't actually affect the autopilot at all. No light illuminates or anything, despite the button push animation happening. 

How strange!
