-37 elo for winning???

I stumbled upon one of my favourite chess commentators David Howell and when I tried ro play him, it showed -37 for a win, -18 for a draw and +0 for a win??? The game was aborted as I was absolutely stumped and I don't hate elo that much. But can someone from chess.com explain this to me and I hope I can play David Howell again someday
There was a visual bug that has been fixed. The actual rating changes would have been correct.
