How to restore my theme settings after click activate base version

Hello,

I have made several changes to the theme settings.

However, I accidentally pressed the “Activate Base Version” button and then some of the changes I made were gone and returned to the default settings.

Are there steps to restore the settings that I have done?

Note: maybe you should also add a warning or notification before clicking on the “Activate Base Version” and “Set up Version” buttons.

Thanks.
