我有一份主要用德语撰写的文档。因此，将设置ngerman为文档的主要语言babel是理所当然的事情。
然而，在引用的 100 多篇文章中，只有大约 5 篇是德语文章，并发表在德国期刊上，而绝大多数文章都发表在美国或英国期刊上。因此，将少数德语条目设置american为主要语言biblatex并使用是有意义的langid = {ngerman}。以下是 MWE：
\documentclass[american,ngerman]{scrreprt}
\usepackage{filecontents}
\begin{filecontents}{test.bib}
@ARTICLE{pollack.2015,
author = {Ari Pollack and Bibhu D. Mohanty and Rishi Handa and Patrick M. Looser and Valentin Fuster and Spencer B. King and Samin K. Sharma},
title = {Preventive Stenting in Acute Myocardial Infarction},
date = {2015},
}
@ARTICLE{white.2014,
author = {Harvey White and Kristian Thygesen and Joseph S. Alpert and Allan Jaffe},
title = {Universal {MI} Definition Update for Cardiovascular Disease},
date = {2014},
}
@ARTICLE{green,
author = {Herbert Grün},
title = {Ein Artikel},
date = {2016},
langid = {ngerman}
}
\end{filecontents}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{babel}
\usepackage[backend=biber,style=nejm]{biblatex}

\begin{document}
\chapter{Test}
Hier steht viel Text auf Deutsch und es gibt auch eine deutsche Quelle \parencite{green}. Die meisten zitierten Werke sind aber Englisch geschrieben, so etwa \textcites{pollack.2015,white.2014}.
\printbibliography{}
\end{document}
显然，biblatex和babel不能很好地协同工作。虽然参考书目中的一切看起来都很好，但引用却乱七八糟：
如果我注释掉该行language=american，一切看起来都如预期的那样：
我尝试使用不同的参考书目/引文样式编译文档，既在 biblatex.cfg 中设置了选项，也未设置选项——但除了注释掉语言设置外，其他都没有任何效果。因此，很明显，这肯定与 babel 不兼容。有什么建议我可以做什么吗？
