Hello,
Please ensure that you’re using the latest versions of the plugin, both free and pro.
Please also check if some CSS or JS optimization is enabled at your website, maybe in your theme’s settings or in caching plugin settings. Try to temporary disable it, purge all website’s caches, clear browser’s caches and check again.
If it won’t help please contact us through our internal support and send us URL of the projects you have issues with. We will help you to fix this.
Best regards,
