A Duplicate booking was received

This is a first, haven't seen this one before. In my understanding, I should NOT see anything like it ever, as at its core, that's what OR should prevent: double bookings.

(see attached screenshot)

I message this guest using BDC admin portal. That also seemed to make OR trip really bad since now inbox has a message without a booking, so clicking on that message just causes the interface to spin endlessly 

what now? BDC admin portal does not allow me to cancel this reservation since is handled by OR and OR is freaking out.

Hi Alin,

Please email help@ownerrez.com with this guest's details so we can investigate and discuss booking specifics that we cannot talk about over a forum post.
