Weekly Discount:
It looks like you may have smart pricing turned on. Log into your admin panel to look at your calendar. Then click the link "Manage Settings" on the right side under the charcoal menu. Next click the Pricing tab. Make sure Smart Pricing is turned off.
10% Discount:
The 10% discount is by Airbnb invitation only. Navigate to your calendar. Look on the right side of the calendar and see if there are any booking suggestions there. Occassionally the suggestions may be to change your price or to give a 10% discount on a specific day. Sometimes if a guest cancels and the reservation is only a couple days away then the 10% offer will appear.
If it makes you feel better, I have never had anyone make a reservation to get the 10% off yet.
