Community taxon is displaying higher rank than it should be

I found a probably similar case here: a moth was observed and labelled Lymantria dispar, then somebody disgreed and said genus Haploa, then the observer withdrew the initial ID. Now the website shows “unknown” as community taxon. I’d have expected either “Haploa” (since Lymantria was withdrawn) or “Erebidae” (the smallest group that contains both). Could someone explain what’s going on?
