You and I have non-US listings, @Pauline106. It has to do with exchange rates and rounding. The system, as I understand it, converts to and from the US dollar even when someone like me, in the same country and using the same currency as you, looks at your listing or books with you. The odd time it will add a dollar to mine, but more often takes away a dollar. There is nothing to "fix", so it will do no good to keep contacting Airbnb. I wish they had explained it when you called.
