Your listing shows $37 USD per night, but when I look at specific dates on your calendar it shows me $38 USD per night. My thought is that you may have set your nightly price under the price tab to one thing and then set the specific days on your calendar to something else.
Price tab: navigate to your calendar in the admin section, click price settings in the grey menu bar. Check your nightly price setting.
I am having the same problem. I have checked all the places to reset things and still no change on the map. It should be $70 and it's still showing $90. I have never even charged that so I don't know where there number was generated from. Does it add the cleaning fee? Even so, that should have changed because I lowered that rate too. This website is aggravating and there doesn't seem to be anyway to even contact Airbnb!! Anyone know of a way to get them directly or are all the hosts just supposed to suffer things out with inaccuracies??
