To get rid of the old shares that are lost requires you to use a terminal program like putty to ssh in the shell. You have to up your access rights to admin/root once logged in. Then you need to backup to the root directory. Under the root directory there will be a folder called "hd" this is where you will find vol-md0 and all sub shares. Then use the rm /"share or folder" -r . This will remove shares and all files from the snap. Use "" if you are deleting file/folders that are 2 words. the -r flag forces it to delete folder that are not empty. Remember in the Linux/Unix world it's case sensitive and is not forgiving. So make sure your right before hitting the enter key.
