This is not Airbnb itself, but the community
Promotions can be set AND removed in the calender of your listing.
But i looked at your listing and there are no promotions.
If you mean the monthly discount (which is set to 30%):
It can be removed (or lowered) in the price section.
Please note if you do not offer a monthly discount at all, your listing will no show up in the search system for stays longer dan 27 nights (which you do allow now)

Hope this helps
