T440p and Ultradock

Hi everyone ! :) Hope you are all ok .

I run Catalina on a T440p smoothly so far. I bought an Ultradock, video works fine (usb are not recognize but i've seen a guide to solve, i'll have to put myself to it) , but the main issue is : when i shut down the computer it restarts, i can never shutdown when it's on the dock, appart from the shutdown button manually. Anyone has a way to solve this ?
