I think there was some kind of re-indexing issue after some of those higher level taxa got swapped around. I reindexed everything in https://www.inaturalist.org/taxa/500752-Fionoidea and it seems to look better now.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
@kueda taxon 627586 seems to have a lot of parent taxa still set which are inactive taxa https://www.inaturalist.org/taxa/627586-Gulenia-orjani
