Sudden problem opening key editor

I’ve used Cubase 11 previous versions for years, and have always opened the Key Editor to appear on the individual instrument tracks – so the project window shows all the track key editors at once. All my shortcuts and custom settings have just disappeared, and one of them was the ability to do the above. I’ve always opened the key editor by double-clicking on each track. But now it opens that track’s editor in the lower zone, which I presume is the default. The manual shows the only other option is to open the key editor in a separate window. How do I get back to opening it by individual track, so all the tracks show at once the key editors open?

You are referring to what is called the in place editor, as opposed to the key editor.
