In my experience [number]@ are duplicates of bookmarks that have the same IP address, eg for situations when there are multiple bookmarks to different locations on the same IP address or multiple bookmarks to the same location on the same IP address but with each bookmark having different advanced settings. In your case they may be duplicates of bookmarks with the same domain name or something like that.
