Rode os comandos no power shell
It seems that when adding the extra language it also installs an extra windows store package -> Microsoft.LanguageExperiencePack
It seems that this is changed in build 1803:

In our image we always removed everything which had to do with the windows store.
We now fixed it by removing everything from windows store again after adding the language pack.
Remove everything:
comando: Get-AppxPackage -AllUsers | Remove-AppxPackage
Provision remove everything:
comando: Get-AppxProvisionedPackage -online | Remove-AppxProvisionedPackage -online
