Please send me a screenshot of the issue.
]]>To rule out the possibility of a plugin conflict, please deactivate all your plugins (besides Elementor) and see if it helps. If it solves the issue, reactivate them one by one to find the culprit. If it didn’t help, switch your theme (temporarily) to a default WordPress theme such as Twenty Sixteen and see if it makes any difference.
If the issue persists, please try this guideline:
Regenerate the CSS via Elementor > Tools > Regenerate CSS on your WordPress Dashboard. (Make sure to back up your site).
Go to Elementor > Settings on your WordPress dashboard. Click the Advanced tab and then switch the CSS print method to Internal embedding.
Clear all cache: your browser’s cache, other plugins’ cache, and server cache (if possible) I Make Changes and Nothing Happens.
Check the issue from a different browser or incognito mode to rule out the possibility of browser addon conflict.
