I don't understand why this calculator (correct me if I'm wrong) was never recalled to remove at least the most important bugs....

That's one reason why companies use rewritable firmware chips now. It would cost too much to send out a new batch of calculators but the cost is reasonable to create new firmware, make it available on the company website and have people download and install it themselves.
