Yep. Folder-in-folder syndrome, we call it.
Some extraction utilities create an extra folder named after the .zip file, just in case files are loose inside the .zip. Even the default Windows one does this. In Windows, if you right-click and choose "Extract All...", a window pops up asking you where you wish to extract to. But you don't want to extract to a new folder named after the .zip file, so you need to remove that last folder name from the path.
