As a new host there are many, many things that will baffle you about the system. I hope you will take time to read all the hosting articles you can in the Help Center. Mistakes can have both short term and long term consequences. Just a thought.
Without sufficient information about the payout you did get versus the rate, I can't venture a guess. That is good as these type of questions are best posed to Air BNB. Contacting Air BNB options are spelled out in the Help Center. I have heard that the best response for most issues happens when the Air BNB Twitter account is used.
