Airbnb changes calendars’ set prices regularly

Hosts, If you haven’t noticed Airbnb will change your set prices so they can sell the room. It seems there is an algorithm that lets them override your set price so the room will be booked. I offered a holiday weekend at a high price. Frankly, I didn’t care if it rented or not, so I set it high. The rates were fixed, not variable, and about $20 more than my usual rate. The room was rented for $10 per night less than my “set” price. This times four nights =$40. I doubt the company kept this money but rather they made an override so the room would be rented. I have initiated a service ticket for this. I was looking back at my bookings and noticed actually a number of nights that were let for odd numbers that ended in cents and were not the set prices of the calendar. If they are going to do this we should be notified. Otherwise it is at worst fraudulent.
