Domain already listed???

I just transferred a domain back to godaddy. I am trying to list it on auction, but their system is stating that is already for sale??? I had it on weebly before the transfer. I had it on godaddy before i had it on weebly. And now it is back on godaddy. Has anyone ever encountered this issue? I created the domain and i have been the only owner of the domain. The support at godaddy is telling me that weebly could have listed it? i am confused about this. I may have listed it before on godaddy before i transferred it to weebly. The transfer did complete and the domain is showing in my godaddy account. Any help is appreciated.
