Windows 10 1903 Display Language not defaulting to Regional langauge

Hello Team, 

Appreciate if someone can help me out of this issue.

Problem : We have different language packs to be applied in customer environment as part of the TS ( SCCM 1906 ver) with WIn10 1903 Enterprise OS, Language packs along with FOD's/LXP's are getting installed perfectly via TS.

I am using Dynamic variables and unattend .xml to set the language settings, everything looks fine but the OS is always defaulting to English as Display language and not the Regional language.

Input/keyboard/regional settings are defaulting to regional except UI( Display ) which is not setting to respective regional language.

Please find below the unattend.xml and TS settings.  End result should be Display UI setting to default Norway but its not happening right now, tried using powershell command which doesn't either set since it sets for user not system.

Please suggest.
