Beechcraft C90 King Air

I submitted several exhibits to an aviation museum. One of them was rejected on the grounds that it was temporary. However, the planes have been there for many years. I then decided to appeal the submission.
With the reaction that Niantic has now rejected it as a duplicate.
The problem: I have no idea what it's supposed to be a duplicate of. Because this plane is not yet a wayspot.
I once sent the photos to a friend and asked him to try it also, but I don't know if he did it.
In any case, I would like to know what happened to my proposal. I had a suspicion at first that it might have been rejected as a duplicate by the museum building, but even there I don't see my photo.
Can anyone provide clarification? If this proposal has been unlawfully duplicated by the appeal, then I would like the appeal's decision to be reconsidered. Thanks.

I've checked the Wayfarer app and I can't find your photo on any of the nearby wayspots. I did find an issue which might not have helped you though. If you go to the coordinates you provided on Google maps, the street view defaults to a photosphere which is nowhere near your nomination. The red pin is the coordinates you provided, whilst the blue and white arrow is where the photosphere is located:
Ok, now that's weird! Another appeal was rejected as a duplicate, but this time definitely justified. The photo does not appear on the associated Wayspot either. I'm starting to suspect that there's an error on Niantic's side while working on appeals.
@NianticAaron Can you investigate?
