How to stop windows 10 adding %USERPROFILE%\Documents to Document library

I’ve been using windows 10 for a few months. In the past month. It has started adding %USERPROFILE%\Documents to my Documents library every time when I log in. I don’t want this to happen.

The directories I want in my Documents Library are
%USERPROFILE%\Documents\Documents (default)

I don’t want %USERPROFILE%\Documents in the library because Windows and various applications put subdirectories there that I hardly ever need to look at (Scanned Documents, Fax, of Downloads, etc.) I put my real documents in %USERPROFILE%\Documents\Documents.

For the past month or so, Windows 10 has added %USERPROFILE%\Documents to the Documents library every time I log in and also made it the default save location. If I remove it from the library, it is added again next time I log in.
How do I stop this happening?
Thus anyone know who to fix this issue then please suggest me
Thanks a lot in advance
