I discovered that the issues you mentioned earlier were caused by third-party plugins you installed later. When I deactivated all plugins except the theme’s required plugins, the design-related problems were resolved.
If you need any licensed plugins (such as Amelia, Tutor LMS Pro and etc.), please let the developer know by replying to the topic linked below. He will provide you with the necessary licenses:
