Kate, Thank you!
I was unable to delete a duplicate with/using my laptop.
Downloaded the AirBnB app (android phone) and it took a couple of tries, but finally worked.
Initially it wanted to 'allow' me to create a Duplicate of the duplicate!
p.s. also required to create a password (?) in email link.
Created a password that- then would not be accepted.
not super user friendly, as a first time BnB'er
Thanks,
I would not have known what to do!
Donna
