That is happening to me also.
There is another problem with relisting from the closed auctions page. Because all the auctions that ended do not have the shipping time entered they are all failing when trying to relist.
There needs to be a way to change just that field with out using a profile. The only way to fix this on a large scale is through a profile. I have many items in a folder with different shipping profiles attached to them. If I can just change this field it would be a lot easier.
