Android download manager saving two file but linked

Question

So, I'm implementing download manager to download pdf files and save it on specific folder. But, what happened is android download manager is download the file, then create a folder, and theres also the same file there and outside of it. But when i delete one of them, lets say John_Pdf on root download folder, the one on partner-wht is also gone.

val downloadManager = context.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager

for (i in downloadUrl.indices) {
val request = DownloadManager.Request(Uri.parse(exampleURL))
                .setTitle("Document")
                .setDestinationInExternalPublicDir(
                    Environment.DIRECTORY_DOWNLOADS,
                    "doc" + File.separator + "document"
                )
                .setMimeType("application/pdf")
                .setDescription("Downloading Report")
                .setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
                .setAllowedOverMetered(true)
                .setAllowedOverRoaming(true)

downloadManager.enqueue(request)
