Player history duplicating in editor

The history of every player I add into the database is being duplicated along with non playing history and relationships. I've already deleted all the duplicated records once but they seem to just come back after saving, exiting and re-opening. Does anyone know why this is happening and how to stop it?
Thanks.

There are issues with adding a language too it duplicates
