Accounts :: SYSTEM Owns User Folder On Drive D

I recently installed Win10 on a C SSD and set a D hard drive for my data. I have assigned default save to be D. FYI, I do have a C:User[name]Documents, Pictures, etc. also.

However, I found that on my drive D, there is a D:[name]Documents, Pictures, etc. So I included the sub folders into the Library. However, the D:[user]Documents folder does exist but I cannot change the permissions at all (Read Only). It is owned by the System.

Don't I need to take ownership back to make use of it? But how? Or do I just leave it alone. Right now, all save documents are going to C:[user]Documents. Other D:[user] sub folders, i.e., Pictures and Videos, are writable.
