Question about Wandschalter Modul - 432182

I have installed a wall switch module on a combination switch with push button and simple socket from Feller. Now I have the problem that my push button does not work properly. Despite the button setting in Hue, the switch dims to 1% every time it is pressed. To switch the light on or off I have to press twice briefly. If I set the push button (really a push button) in Hue to toggle switch, everything works. For scene changes I have to do on-off-on-off, i.e. click 4 times for the 2nd scene. Does anyone know how I can make the button really a button?
