CEC powers on projector even though option is deactivated

Hi, I have a problem with a RPI2 and the CEC module. Every time I reboot the Pi or I do a clean boot the Pi/OSMC triggers my projector and powers it up. I set the option not to anything on start in the CEC module but it doesnt help. I also cant deactivate the CEC module as I am using it :confused:
Any ideas on this?

Please try to disable “Beim Starten, Kodi als aktive Quelle melden”. But I’m not sure if cec will work after that…
Does it solve your problem?
