Tooltips only show title

Hi,
I’m using shortcodes which look like this: [glossary slug=’national-industrial-recovery-act-1933′]National Recovery Act of 1933[/glossary] and have tried setting tooltips to either excerpt or full. In both cases, the tooltips appear on hover showing the title but below that the initial message “loading glossary term” and then the area goes blank and what remains is only the title.

Here’s the page where I’m testing: http://72b.45c.mwp.accessdomain.com/test-page-new-deal-programs/

Thanks!
Lisa
