Hi There @cglleadsllc
Thanks for writing in! First of all, pleas update your Pro theme to the latest version as you can see the latest version information from here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195). You can follow our update guide here (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62).
To troubleshoot your issue further, you need to remove all of your custom CSS rules added into your site and test your issue again.
If you’re still having issues, then you can disable your 3rd party plugins (except Cornerstone plugin) and see if you’re encountering a plugin conflict. If the issue resolved, then you can activate your plugins one by one to see which plugin causing this issue.
Also If you’re using a child theme, you need to disable your child theme temporarily and activate your parent Pro theme by head over to Appearance -> Themes section. If the problem resolved when testing, then you need to check your child theme customizations to isolate the issue.
Please make sure to clear all caches when testing your issue by following this resource (https://www.wpbeginner.com/beginners-guide/how-to-clear-your-cache-in-wordpress/).
Let us know how it goes.
Thanks!
