Redundant writing credits on merged title

https://www.imdb.com/title/tt0083613/fullcredits/ The title above was merged a couple of years ago. There used to be a separate title page that was classed as a feature film rather than a TV episode. Most likely as a result of that merge, each of the three writers credited on the film are credited twice. I tried to delete the redundant credits and it came back declined almost immediately. I've never seen that happen so fast. Clearly, this contribution was not handled by a thinking human being. Contribution #250320-190331-453000 P.S. This website was down for weeks, and when it comes back up, all of the sudden, nobody can include images or links in their posts/comments? What the hell is going on?
