[Bug] Button becomes disabled after clicking the "Add Section" button (varies by browser)

After clicking the "Add Section" button once in the website editor, the button does not become active again, requiring the user to refresh the page each time. - Findings: The button works normally in the Edge browser, but the issue occurs in the user’s previous browser (presumably Chrome or Whale). - User Request: Please implement an improvement so that the button remains active reliably regardless of the browser environment.
