Duplicate taxon on checklist

I’m browsing a checklist called “Indonesia Check List” and noticed that the species Salvia misella is listed twice, here and here.

Basically I was trying to edit the Establishment Means, but I got an error saying “There were problems updating that listed taxon: Taxon is already on this list” — likely due to the duplicate. I wonder what might’ve caused this? A taxon swap, maybe? In case I encounter this again in the future, what could/should a regular user like me do?

Thanks!
