Was that judge filling in the wrong column for 4 rounds?

How on earth has that judge scored the first 4 rounds for Wilder? they weren't even close. Anyone remember a fight between Burnett and Haskins not long ago? - One judge was filling in the wrong sides of the scorecards and it ended up as a split decision when Burnett won by a total shutout. So one judge had Haskins winning every round by accident. It was bizarre, but luckily it didn't affect the overall result. Part of me is thinking that this judge had been filling in the wrong sides and realised after 4 rounds and then started doing it properly. It's the only way i can explain how it's possible to give Wilder the first 4 rounds.
