Missing last letter of actor's role after scraping/rescraping

After scraping (or even using Rescraping Specific "Actors") for any TV show (to be used as a NFO file for a dvd that has TV episodes), the last letter in every actor's role is missing.

It does not matter whether the actor's role has 3 letters or two longer words. The last letter is not there.
Even editing of the "role" name (little bit difficult for tens of actors' names) is not possible.

Is it a bug?

P.S.: I organize most of TV shows as movies (based on DVDs, not based on episodes under TV Show tab).
