Cubase LE 13 - Show/Hide MixConsole Toolbar - not working

Hi,

i noticed that the button to show/hide the MixConsole Toolbar in the Lower Zone doesn’t work in Cubase LE 13 (latest version 13.0.30.).

It does nothing.
In a new project: I can’t show the toolbar.
In an old project from an earlier version: I can’t hide the toolbar.

Is this a bug or a wrong setting?

I’m on Windows 11 23H2.
