Hi, thanks for the report. I noticed it myself a few days ago but I can't seem to figure out why it is periodically doing this on-and-off. Still investigating.

Perhaps it's part of the update process where when the data is being updated in the database, first the new names are being added to the database then a person downloads a copy of the list of names and after that deleted from the database is the old names. Just a theory of the duplicate names but that would be my guess.
