Thank you for posting in Microsoft Q&A forum.
But for some servers its not getting installed and it says compliant in SCCM server.
Where did you see the compliant status in SCCM? How many clients show required or not required for the updates you have deployed?
And like RahulJindal said, current branch 1802 was ended support on 22 September 2019, it's recommended to upgrade to the latest version as soon as possible.
