As the topic says, after some deliberation I took the above decision. The problem with those two categories didn't occur to me until a particular user started putting every Yo-kai that isn't obviously feminine into the "Male" category. To begin with, Yo-kai aren't even human and a lot of them are objects to which gender/sex doesn't even apply. So before said user puts, say, Arachnia in the "Male" category and we REALLY have a problem, I'm nipping this in the bud. I'll keep the equivalent categories for human characters otherwise. I hope you'll understand.
