Problem with Folder Name

[dannySB]

Hello,
The problem I have is the following:
I have laptop with Windows 10, couple months ago I had a problem with adding something in the Downloads folder and I did something, somehow. Now every folder (Downloads, Documents, Desktop, Pictures etc.) is named Documents and can’t be renamed, but when I open every single one of the folders it shows what I have on my desktop.
The second problem is that since then there is an empty folder, named Downloads and every time I delete it, it shows after a couple of minutes again.
Please if someone knows how to help, write me!

@dannySB try deleting (or start with renaming) hidden files desktop.ini. My desktop-folder contains a desktop.ini with the following content:

[.ShellClassInfo]
LocalizedResourceName=@%SystemRoot%\system32\shell32.dll,-21769
IconResource=%SystemRoot%\system32\imageres.dll,-183

Is specifies what name and icon should be displyed.
