Caption in lightbox

you can use instead this snippet to remove the titles:

function temporary_removal_title_tags(){
?>
<script>
  window.onload = function() {
      var links = document.querySelectorAll('a, img, *[title]');
      for (var i = 0; i < links.length; i++) {
          var link = links[i];
          link.onmouseover = function() {
              this.setAttribute("data-tooltip", this.title);
              this.title = "";
          };
          link.onmouseout = function() {
              this.title = this.getAttribute("data-tooltip");
          };
          link.onmousedown = function() {
              this.title = this.getAttribute("data-tooltip");
          };
      }
  };
</script>
<?php
}
add_action('wp_footer', 'temporary_removal_title_tags');

but a lot of enfold elements have a choice for showing instead of the title f.e. the description.
