Hello,
Sorry for the inconvenience but firstly, we noticed you were using two Page Builders at the same time on your Elementor & WPBakery both. Also, you had Elementor Pro activated too. So, we deactivated the WPBakery on your Site and the remaining content on your Site which was missing appeared then.
Further, the LiteSpeed Cache plugin was also causing the conflict on your Site so we deactivated that and now your Site Layout appears fine.
Please check back your Site after completely clearing the browser and server cache.
Best Regards.
