Windows 10 2004 : No more Administrateur

Hi,

I'm French and use MDT to get a system image of Windows 10 2004.
I use SW_DVD9_Win_Pro_10_2004_64BIT_English_Pro_Ent_EDU_N_MLF_-2_X22-29752.ISO and the language pack Microsoft-Windows-Client-Language-Pack_x64_fr-fr.cab found in the multi-language iso
I use it in the customsettings.ini :

UILanguage=fr-FR
LanguagePacks001={fd55e77c-40aa-4174-9409-222785d3b710}

And it is well installed.

But I discovered that in the build 2004 the local administrator is named Administrator when in the build 1909 the local administrator was named Administrateur

Did I missed something ?
Or is it normal now ?

Thank you for your help.

Ludovic.
