I believe I simply opened CodeLab (Effects-Advanced-CodeLab...), started with the code that defaulted in the editor, made my changes and saved it. However, when I do the same thing now, it works fine 🤷♂️. You may be right. Perhaps my short term memory is failing 😄. Thanks for looking.
UPDATE:
I've tried a few more times using default code, new through the menu, and the new toolbar ensuring it was unchecked (trying first ticking it and unticking it). I have only gotten the radio buttons enabled a few times. I can't find any repeatable behavior enabled vs disabled. I'll update again if I find something repeatable.
