Identification counts

I’m finding it odd that INaturalist isn’t counting my identifications correctly, or at least so it seems. For example, there are only 19 observations of the beetle species Donacia caerulea. I have identified all of them, but in the Top Identifiers section I’m credited with just 12. Elsewhere n the subfamily, there is a similar discrepancy at all taxonomic levels. Trying to understand why this is, can anyone shed light?

It seems you need at least one agreeing ID.

The Top Identifiers section is only counting Research Grade observations.
