Scoreboard name duplication

I have a game setup and I had the score showing in the "list" and "sideBar". When i clicked tab to see the list score, it duplicated my name on the sideBar and it sets it to the score of what the list is and it won't go away until i reopen the world.

• Also, it looks like it's happening because in the "list" menu, it was displaying as "0" (Which is also another bug)
• And i was able to get the name there 3 times when switching teams
