A particular listing gets approved, then shifts to declined. Twice.

In a slight continuation of problems that were described in this thread, a recent string of legit listing deletions (which reoccurs from time to time on my personal page and some of my productions as well), my uncredited additional crew listing for Bohemian Rhapsody (2018) got deleted. Since it is not the first time it happened, I habitually took the same proof (copy of a confirmation letter from 20th Century Fox at the time), reuploaded it and got it approved, again. 

Several days later, the credit vanished and a previously approved submission (#220212-223426-243000) bounced to Declined with no reason given. Same exact situation happened with the next attempt (#220215-223349-009000). It is the first time I even encounter a function of reverting from approved to declined which I was not even aware was possible, but it seems to be now lingering over every single addition of this particular listing, with #190723-195019-193000 and #210507-015329-685000 also appearing as declined. Internal data that it was on my page is still very much there, because in both brief cases of reinstatement of this listing it automatically appeared on my "Known For", since it is set as one of the four titles to be there on my IMDb Pro so far. 

My initial thought was that I've encountered a feature that is in testing or is there for a while, but I haven't seen it yet. But if that's so I fail to comprehend why this feature could be in place. The whole purpose of "Track Contribution" at times is to compare where and which of them went wrong, so having a string of similar (not identical!) contributions appearing as "declined" will just mess the usability of the feature. If that's not the case I am not sure what to think of it. Woking theories include me being 'lucky' enough to stumble upon a major glitch or, well, someone using a hack and/or a loophole IMDb is not aware of. The latter is more likely considering the persistence of someone who loves to mess with my IMDb pages. 

For context, the circumstances of a lot of people lending their voices to production was at the time very much publicized and it seems that none of the other people who chose to add themselves to the production in that capacity on IMDb have my problem. It's not a particularly important listing to have on a page, but it's a cherished one since movie kinda helped me through a rough patch in 2018 and I was always a fan of Queen. This is literally being a part of the scene and while no one can't quite take that moment away from me, it is also a legit listing per IMDb guidelines.
