Issue with thumbnail descriptions

I am having an problem that I cannot figure out for the life of me. I have set this plugin up recently and for the most part it works fine. Except, some of the description text is not showing up in my thumbnails. I have 40 videos in my gallery and 11 of the thumbnails do not show the description text, funny thing is the description text for these thumbs show’s up fine in the player.

I have looked at the settings of the individual videos and have found nothing different with them. Any ideas what could be the issue?

I could provide a link if needed, but it is in the staging process now and not live yet.
