Can't access Channel Strip

Hi everyone,
Loving the new Cubase here, but I got an issue, can’t find the solution and didn’t see anything in there about it (or I haven’t looked hard enough !). I can’t open any channel strip plugins. I can choose which one I activate, I can right click on it and access presets, but I can’t open the actual control panel of the plugin. Any help ?
Thanks :slight_smile:
