We are having some weird issues with FDS FCU (older version, unsure exactly what version will update when I have that info.)

When we launch P3D and FMGS we can use all the INPUTs for the FCU but none of the Segment-displays are outputting anything or the backlightning of the buttons either.
When we assign it through IIT_Creator everything lights up correctly icluding segment-displays and backlight for buttons.

We've tried using both Legacy and New module for FDS without any luck.

Additonal information:
OS: Win 10 x64 (latest release)
Sim: p3d v4 (latest)
FMGS: Latest

Best regards, Kristoffer
