Dear @_skjul_
It should be working the way you wish: Screen Shot 2020-12-30 at 9.30.35 AM.png
Are you able to post a link to your website?
Also does any of the help on the This page apply?
https://laytheme.com/troubleshooting.html#customizer-does-not-show-up
& just to be sure as you mentioned above:
Wordpress, Lay Theme & Laytheme's Addons are all up to date? Any Custom CSS or JS that may interfere is temporarily removed. Any third-party plugins de-activated to see if this resolves the issue. License key not activated - (in website blank situations or button not available)Let me know and best wishes!
