Hi @Gerry-And-Rashid0
Actually happen to me too a month ago, but in my case I canceled the other pre-approval in time and inform the guest that the room was taken.
So pratically the other guest could still book my place, even if the first guest confirmed just 10 minutes before.
I think most probabily there's a bug on the system in the last few months. before never happened to me either.

I suggest to write on Airbnb twitter or fb, or try to call... I dind't find any number for Thailand, so if you want call them, try the australian number:
