Homepage header cover image not showing

Hi team, I am using Catch Bells theme, and the website is experiencing an issue with uploading the cover image for the homepage header on both laptops and mobile devices for a few days. I tried to disable Lazy Load Images in W3 Total Cache, and I can see the image on the site when I log in to the WordPress admin, but it still does not work on all other devices. When I enable Lazy Load Images, I can't even see the image on the site when I log in to the WordPress admin. All other images are showing as normal when Lazy Load Images is enabled. Here's the home page https://sydyachtclub.com.au/ Is this something that you can help me with? Thank you so much.
