When inserting a single image into a row, it's not showing up when saved.  When we review the CSS, we can see that the opacity for the element is set to 0.  We didn't set it to 0 and don't see anywhere for it to be changed.  However, we can see that line 8094 of style.css set's it equal to zero even though animation is turned off.  Included is the CSS code..

img.img-with-animation, 
.col.has-animation, 
.wpb_column.has-animation, 
.nectar_cascading_images .cascading-image .inner-wrap, 
.nectar-fancy-box.has-animation{
  opacity:0;
  position:relative
}
