Hello @LeahVachani,
Please temporarily deactivate your caching plugin and test your site again.
And by the way, please make sure that those images exist in your server. It may have been removed or corrupted. The last time I check, the image does not exist:

If still not showing and working, please provide us access of your site in a secure note so that we can check it.
To know how to create a secure note, please check this out: https://theme.co/apex/forum/t/how-to-get-support/288
