Adaptive Images Sort of works

The first page of my website does not appear correctly on small screens. The other pages are acceptable but could be better. Can you please take a look?

? PHP GD library is installed.

? Image cache directory has been created.

    /home3/rdmanage/northbeachrentalresponse.com/wp-content/cache/adaptive-images => drwxr-xr-x

? Installation .htaccess file is setup OK.

    /home3/rdmanage/northbeachrentalresponse.com/.htaccess => -rw-r--r--

? Adaptive images settings dump:

    array(14) {
      ["resolutions"]=>
      array(3) {
        [0]=>
        int(1024)
        [1]=>
        int(640)
        [2]=>
        int(480)
      }
      ["landscape"]=>
      bool(true)
      ["cdn-support"]=>
      bool(true)
      ["cache-directory"]=>
      string(21) "cache/adaptive-images"
      ["watched-directories"]=>
      array(2) {
        [0]=>
        string(18) "wp-content/uploads"
        [1]=>
        string(17) "wp-content/themes"
      }
      ["jpeg-quality"]=>
      int(70)
      ["sharpen-images"]=>

      ["watch-cache"]=>
      bool(true)
      ["browser-cache"]=>
      float(180)
      ["hidpi"]=>
      bool(false)
      ["version"]=>
      string(6) "0.6.68"
      ["sanitized"]=>
      bool(true)
      ["wp-content-dir"]=>
      string(55) "/home3/rdmanage/northbeachrentalresponse.com/wp-content"
      ["wp-content-url"]=>
      string(47) "https://northbeachrentalresponse.com/wp-content"
    }
