Golden Records has a master list of rounds that are updated periodically.  This list is loaded into Golden Records when first used.  Subsequently any changes to the master list have to be added manually.

Go to https://archery-records.net/clubs/rounds or https://archery-records.net/personal/rounds and open the Manage Data toolbox at the top.  Click Load Missing Rounds to show a list of rounds in the master list that are not in the local list.
