I had hundreds of relistings to do.
Attempted to do them the usual way by clicking 'delete' and 'relist'
Then went to 'auctions I ran' and all the relists were still there with the 'relisted' message
Deleted all of them again and got the message that none had been deleted...and they remain in the auctions I ran list.
Giving up now and will try again some other time.
