Cast Lists Being Listed Alphabetically

Today I noticed that the cast lists from certain films (in this case, "Slumdog Millionaire" and "Licorice Pizza") are not currently being listed correctly when I go to the view. The cast and crew page will list one or two stars from the film, then list every actor alphabetically and say it's "complete, awaiting verification." What? How did this happen? The credits have been verified for a long time, why are they being re-verified now? I do notice that both films list their actors in order of appearance rather than any hierarchical system that is common for credits, but that's still a bizarre reason for this to be happening. I guess I'm just curious as to why this happened. It is annoying, especially because this is the only site I know of that lists credits in the same way the films do, but I am assuming this is a temporary issue. It seems odd that something that's been settled for years (over a decade and a half in the case of Slumdog Millionaire!) is for some reason not settled anymore.
