First of all, please make sure that you have fully updated by following our version information guide here (https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195) and then follow our update guide here if required (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62).
After an update, you need to clear all caches before testing your site. Please follow this resource on how to clear full cache (https://www.wpbeginner.com/beginners-guide/how-to-clear-your-cache-in-wordpress/).
If you’re still having issues, try removing your custom CSS rules added to your site temporarily and test your issue further.
Further, you can also disable your 3rd party plugins except Cornerstone plugin to see if you’re experiencing plugin conflict. If the issue is resolved, then you can activate your plugins one by one to see which plugin causing the issue.
In case if you have an active child theme, you also need to disable your child theme temporarily to see if your child theme customizations causing the issue.
If you’re still having issues, please provide us with an example page URL of your site to investigate this issue further.
