Leaderboard showing wrong player name

I joined my own game and the topbar / leaderboard is showing my name as ‘Player’. Apparently it’s not showing up this way for anyone else. I can’t seem to repro it consistently and the console’s not showing anything out of the ordinary.

Is this possibly because of testing the game in studio, and then when the data saves in studio, it saves the name “Player”, to your userid?

It’s the stock leaderboard, so I’d be surprised if that’s what it was.
