I, too, noticed that no candidate other than Biden had picked up votes. The probability that no other candidate would pick up even one vote (even by mistake, in a legitimate count) is so astronomical, it's more likely that someone would win Powerball, MegaMillions and the Publisher's Clearing House Sweepstakes all on the same day.
It's a pretty sad comment on the quality of the fraudsters when they don't even try to hide it.
