Nuki Opener makes the doorbell on the appartment door quite


I installed a Nuki Opener successful at my home. It works fine for the door bell of the house door (ground floor). But the door bell in the third floor is not working anymore. What is wrong? I attached photos with the wiring and the intercom model. Thanks for your help!
