Cubase 9.5 pro

Hello everyone!
I have Cubease 9.5 pro, but I’m not sure it works properly
Some of the things are locked. How to activate them ?
here is an example :
I watched this video https://www.youtube.com/watch?v=5SpQjRkBpAs
explaining how to work with Chord Pads. And when I tried to do the same, some buttons are locked. :unamused:
I had a similar experience with another preset.
Please help if you can.

Hi,

What exactly is locked, please?

Could you write your steps, expected result and what do you see on the screen, i.e. What is different?
