To protect your privacy and keep guests from directly showing up on your doorstep without a reservation your exact position on the map is not disclosed, and the marker is placed a bit off.
In most cases this isn't an issue, unless you have prime property overlooking the ocean, beach, interesting street and the software parks you away from there.
I don't think there is anything you can do about it. If it's really a serious disadvantage you could try to contact Airbnb about it.
