Hi, @Mohamed Kamel
Thank you for posting in Microsoft Q&A forum.
The Required = 0 could means the updates is not required for all clients or the update is not scaned correctly on clients.
If you just synced the Lang packs, you may need to wait for few hours to wait for the clients to scan the update and then update the number of Required automatically.
What is the number of "Not Required" and "Unknown"?

Hi, @Mohamed Kamel
I synced the language packs in my environment and run scan on a client with corresponding OS, it returns "Not Required".
And I found the language packs only have updates for windows 10 version 1709 and previous version, and windows server 2012 R2.
Maybe software updates is not a good choice to install language pack, it' recommended to deploy it as application.
