I know, it doesn't look correct at all. As expected only the left and middle switch work. The right switch does not. I am not sure how to do it correctly. Can anyone give me a hint?

I'm going to do the same installation as you but I have no idea. Did you solve the problem? Did you get the right diagram?

I've found one for shelly dimmer 1:
