In Video Groups, Next/Previous Buttons Overlap Caption

Anybody else get this behavior for videos? The '<' and '>' buttons for next/previous videos (when in a Lightbox group) overlap the caption.

This is the code I changed to put the caption beneath the '<' and '>' buttons in lightbox.css:

#framePrevLink, #frameNextLink {
  width: 45px;
  height: 45px;
  display: block;
  margin-top: 50px;
  margin-bottom: -60px;
  position: relative;
}
