do you have a shop manual? following the bleeding/adjustment
procedures there and consulting the end of the brake section re problems is better than 'thinking' .... there's at least one hole, called a compensating port, don't remember if it's 2 but if that's the way it was when you started, that's the way it should be and not the source of your problem - but improper adjustment when you did the bleeding could well be, and could also mean you now have weeping wheel cylinders because the wheel cylinder pistons were made to move too far when you first attempted to bleed, which should be done after adjusting the shoes up tight
