I think this is not a bug. The "Name" column in 7-Zip means the most relevant file name for any container. For FAT, it uses the long name if it is present, otherwise it displays the short one. The "Short name" column, on the other hand, is FAT-specific and is always populated with the short name. So, when no long name is present, the short name gets displayed twice.
