Bibtex 在未询问时创建子项目？

Question

我一直在努力慢慢地用 bibtex 向我的文档添加参考资料。我创建了这个 MWE：

\documentclass[12pt]{article}

\usepackage[brazil]{babel}
\usepackage{babelbib}
\usepackage{lipsum}

\begin{document}
\lipsum

\bibliographystyle{babplain}
\bibliography{biblio}

\cite{Boulos}
\cite{Lawson}

\end{document}

.bib文件内容如下：

@book{Boulos,
author    = "BOULOS, Paulo",
title     = "C\'{a}lculo Diferencial e Integral",
publisher = "Pearson Makron Books",
volume   = "1",
address  = "S\~{a}o Paulo",
edition  = "1",
year      = "1999",
note     = "380 p",
}

@book{Lawson,
author    = "LAWSON, Terry",
title     = "\'{A}lgebra Linear",
publisher = "Edgard Bl{\"u}cher ltda",  
address  = "S\~{a}o Paulo",
edition  = "1",
year      = "1996",
note     = "348 p",
}

这在参考文献部分产生：

如何摆脱下面那些看起来像子项的东西？
