i have seen this on my server is previous versions, the duplicates tend to dissapear after a while and only usually happen if the server is not shut down correctly.

This is not a bug, this is result of how it was designed. When the server is closed correctly, it can let the matching server know, that it is being closed.
When it just crashes, it takes some time until it is disconnected automatically.
