Price calculation error?

[Ann175]

I have just recieved a booking enquiry for 3 nights. The price for the 1st and 2nd night is $450 and the 3rd night is $442. 

So why is the petential earings showing as $587.00 for each night?

That is about a 30% charge added to each night!! How is that calculated.

This is in addition of course to the $53.00 service fee that is charged. 

Is the nightly charge calculation an error? 

I really struggle with the Air BNB procedures and find it incredibly frustrating that there is no number to call to speak to an AirBnb service staff member. What do that DO wit all of that money they charge? 

Thanks,
