Help! How does a training dummy work?

Hi guys!
I need help. I can not train my skills in bashing.
I have a training dummy, the matching weapon but in the menu the dummy is red.
What am I doing wrong?

Have you set it up through the construction menu (*)?

I have discovered the problem.
I play the German version of the game.
There is no option to select it in the construction menu.
When I switch to english there is one.

Got it fixed, was my fault…
