If you see that a section, row or a module in Extra or Divi theme or Divi Builder plugin appears to be disabled or faded then it will look something like this,

A Divi element (section, row or module) will appear to be disabled (faded) only if its disabled on phone, tablet and desktop in the element’s settings. To enable it again, simply edit the Divi element and scroll down to find the Disable On: settings.

Here enable it for all or some devices. Once enabled it will appear fine on selected devices and then it will also appear like normal Divi elements (unfaded).
