Hello,

If you use Layouts for customizing the product page, you need to edit them via Layouts as well.

They are not designed in a way for setting some conditions via Layots and then editing it via Dashboard -> Products. You just create a Layout, define the condition and then edit that created Layout, thus changes that you made in the Layout will apply to the page/product that you set in the condition. https://prnt.sc/UynYd0It-C4t

Don’t hesitate to let me know if you need any further help or any other info.

Kind Regards
