Possibly you didn't get to two of the message quickly enough and they faded away with the decay of the electrons in the two messages over time. ^&grin
Or more likely a simple temporary glitch in the counter thinking a message had come in when it hadn't, or not reducing the counter after you opened a message.
Best strategy for now is keep an eye on it and see if it does it again.
