I have so far two of these. Both bugged when I tried to upload them years ago (via Ingress). I never got a confirmation email nor did those bugged submissions ever end up in Wayfarer.
Both of these nominations that now turned up lack either of the photos: either the main photo (in which case the supporting image was in place of the main photo) and in the second case the supporting photo is missing.
I suspect that we are just experiencing bugged nominations from a few years back being added into the queue.
