我正在写论文，用的是 LaTeX。我发现参考文献中有一个问题。我使用两种语言来写参考文献：西班牙语和英语，但对于最后一种语言，我无法将单词“En”改为“In”。
这是我的代码：
\documentclass[oneside,a4paper,12pt]{book}
\usepackage[left=4cm,right=4cm,top=3cm,bottom=3cm]{geometry}
\usepackage[english,main=spanish]{babel}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{apacite}
\usepackage{filecontents}
%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{filecontents*}{bib2.bib}
@InProceedings{vallejo:book2014,
crossref = {book2014},
author = {Malaspina, U. and Vallejo, E.},
title = {Creaci\'on de {P}roblemas en la {D}ocencia e {I}nvestigaci\'on.},
pages = {7--54},
language = {Spanish}
}
\end{filecontents*}
\begin{filecontents*}{crossref2.bib}
@book{book2014,
booktitle = {Reflexiones y {P}ropuestas en {E}ducaci\'on {M}atem\'atica},
title = {Reflexiones y {P}ropuestas en {E}ducaci\'on {M}atem\'atica},

\end{filecontents*}

\end{filecontents*}
\begin{filecontents*}{crossref3.bib}
