There are several reasons possible for this:
- The monthly (or early bird or last minute) discount is extreme
- There is a (low) custom price set for specific months
- There is a ruleset applied for certain months or periods with extreme discount or custom pricing.
- A month stay is a "long term stay" and is charged/payed in installments. Be sure to see the correct total breakdown (and not only the final payment, which can be one or two days)
- And finally: there is a glltch in the software !
I can not simulate such bookng, as there is not a 28 days or longer period available on your listing.
I suggest to temporary set maximum lenght of stay to 27 nights until problem is solved.
