Hi, @Bonus12
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"?
