Character Limit Issues

There appears to be a character limit on the “details” section of the team members profile. If you go to the page, and you mouseover Sam Wakim, or Tamara Brown or Anda Ciora you will see that the text just suddenly ends, mid-word. But on the backend, that word is complete. In fact on some of them, it is removing complete sentences. Is there a character limit on there, and how can I remove it? Or is something else causing this, and how can we fix it?
