"Show Code Editor" on "subcards" Greying Out on Vertical/Horizontal/Grid Cards

Hi guys,

After latest updates the “sub card” “Show Code Editor” is unavailable for Vertical/Horizontal/Grid Cards. Now it’s greyed out and it’s unable to be accessed anymore.
Is it happening to everyone else or only with me?
I know I still can use the “Show Code Editor” for the whole Vertical Card, but I find much easier to handle each “sub card” at a time since I have some very long “Vertical Cards” in my setup.
Is this a bug or is it intentional?
Cheers!
