Can't import patches into my WSUS server

I'm trying to patch all of the servers in one of my domains. The WSUS server hasn't automatically downloaded KB4057142, KB4057401 or KB4057402. I tried to manually import the patches and I get error: "This update cannot be imported into Windows Server Update Services, because it is not compatible with your version of WSUS." The version of WSUS I'm using is 10.0.14393.0.

I have another domain running WSUS version 6.3.9600.18694 and I was able to import these patches into it.

How do I get those patches on the other WSUS server?
