Dome light only works when triggered by EFB

[GatlingOrange]

So I have been enjoying the A300 for quite a while now. I'm flying the compatible version on MSFS24 and the lack of proper dome lightning has been annoying to me since the start. However, today I got it working. I'm not sure if it's a bug, a workaround or maybe pilot error. But the following is happening.
 

• Spawning at the gate cold and dark. Switching on batteries, ext-power and dome light. The lights turn on but illuminate nothing:
  
  
   
• Next up is starting the APU. For this purpose I switch to APU-gen and again, no illumination:
  
  
   
• I then switch over to the EFB and select the APU ready state, load it in and all of the sudden the dome light illuminates:
  
  
   
• I then investigated further and went with the cold & dark state from the EFB, turn on batteries and connect EXT-power, turned on the dome and voila, lightning again:
  
  
   

For troubleshooting purposes I reloaded the flight, spawned the plane and the dome light works flawless. Whenever I don't load in any state via the EFB the light seems inoperative and toggling any state seems to wake it up. 

I got the premium version since I really enjoy the A300 and I hoped it would fix the light, but for some reason the premium version runs a lot worse while the compatible version is silky smooth. So I had to switch back.

Bug? Pilot error? Any help is appreciated.

I am not yet able to edit the post, but I forgot to mention that once you swap states, the dome light works for the duration of the sim, regardless of exiting flights. I have to reload the entire sim for the problem to reappear once I've used this workaround. So every time I load in a flight for the first time, you will need to load any state to toggle the light and it will be fixed for the remainder of the sim's running.

Hello,

Myself and a colleague have tried (both compatible and premium version) to reproduce this and to no avail. Have you tried a complete reinstall?
