After you enable Win10 servicing in SCCM, you might get this error on Windows10 clients during update scan.
Reason is-in WSUS, there are duplicate entries for Feature update.....1607 and 1703.

Solution:
You need to go into WSUS console, search for 1607(or 1703), and decline the Feature Update to ....1607. All the results.

Also, try installing this update on the server:
