Why does this "Need ID"?

This may not be a bug, but why does this observation still need an ID? It has three IDs, all the same. Shouldn’t it be “Research Grade”?

The identifications are all at the genus level. It can only achieve research grade status if someone votes in the data quality that the ID can not be improved.

There’s a guide at the bottom right of the page:
