How can I made siunitx not ignore more localisation?

Question

It seem's that I'm doing something wrong for localizing siunitx. What could it please be?

Here is the code:

\documentclass[11pt,a4paper,german]{article}
\usepackage[ngerman]{babel} 
\usepackage{fontspec}
\usepackage{siunitx} %Einheiten
\selectlanguage{german}
\sisetup{
        locale = DE ,
        per-mode = symbol, %nichts ist ^-1 symbol 
    }
%\selectlanguage{german} % oder lokal umstellen

\begin{document}
    Dieser Bereich geht von \SIrange{0}{100}{\joule}

    Dieser Bereich geht von \SIrange{0}{100}{\joule}\selectlanguage{german}
\end{document}

And in the attached picture there is the output using lualatex. The to should be a bis or a symbol like –.

Thank you very much.

Answer 1

Localisation is probably a little misleading here. Siunitx localisation only covers exponent-product, inter-unit-product, output-decimal-marker.

You will have to set range-phrase manually.

Answer 2

Thanks to @clemens I used german with babel and that doesn't work. Therefore using just ngerman (new german, because of a change in spell and grammar checking) localisation works now.

\documentclass[11pt,a4paper,ngerman]{article}
\usepackage[ngerman]{babel} 
\usepackage{fontspec}
\usepackage{siunitx} %Einheiten
\sisetup{
        locale = DE ,
        per-mode = symbol, %nichts ist ^-1 symbol 
    }
%\selectlanguage{german} % oder lokal umstellen

\begin{document}
    Dieser Bereich geht von \SIrange{0}{100}{\joule}

    Dieser Bereich geht von \SIrange{0}{100}{\joule}
\end{document}
