All root files/folders have the plugin folder name in them

I used the plugin to download another plugin, then unzipped it in my local (Mac environment). All the folders and files in the root had the plugin’s slug in them. e.g. files appeared like this: “plugin-slug/file.php” The one in the quotes is the actual filename, it includes the slash in there as well. I had to rename all the root files to make it work.
