Question about taxon changes

General
1

Sometimes the taxon changes don’t actually appear to change anything. For example, I just got a notification a taxon change for the Spoon-billed Sandpiper.

It changed from Spoon-billed Sandpiper Calidris pygmea to Spoon-billed Sandpiper Calidris pygmaea.

No name change, no actual taxonomy change, the only change appears to be in the ID number associated with the species, from 339595 to 979640.

Given that there appears to be no actual taxonomic change, what is the purpose of this?

Is it that there were two entries for this species and they needed to be merged, or is it something else?

Looks to be a spelling correction:

Spoon-billed Sandpiper Calidris pygmea becomes
Spoon-billed Sandpiper Calidris pygmaea

Ah, somehow I missed that little bit. Thanks.

I became a curator recently and things like this and how to fix them were unexpected and not very intuitive for me. Instead of just editing the scientific name, you have to make a new taxon with the correct name and then merge the incorrect taxon into the new one. So in a sense it is
