Buttons control change turns in a key note

Hello everybody!

I’ve got a problem to create and assign new buttons in editor. Each button I make, in the settings I choose control change, and a new adress, like 1CC 28, 1CC 29, it’s okay.
But when I try to assign on ableton, it sees only a key note, like C2. And it sees the same key on all the buttons.
For example, if I assign button one to Mute track one, button two on track two…, any button I’ll push mutes all my tracks!

Do anybody know where my problem can come from?
I work with ableton live 10 on Windows 10 and a Lenovo tablet on Windows 10 too

Thank You.

Problem still here, please help me!

And another one:
When I change the page in edition mode, if I click anywhere, all the screen is selected, and if i stay clicked, the first page module’s settings at this place appears! Impossible to select the module on the actual page…

Thank you

Anyone can help me please?
