I have worked on Law & Order: SVU many times in the past 14 seasons, and I always submit the info to IMBD. For some reason, after the credit is posted for a few days, it disappears. This has happened many times, and not just with SVU. I have worked on SVU 14 times in the 14 seasons it has been on the air. Just last week, there were 5 credits listed for SVU on my page. Today there is only one. I keep re-submitting, but the credits do not appear. This has happened with Nurse Jackie, Person of Interest, and 30 Rock, among other credits. I have worked for over 25 years in the movie and TV business, and I would like to have all my credits appear on IMDB. So, why do the credits appear for a few days, and then disappear?
