该代码运行良好，并且有些代码hyperlinks随处small cap font可见，请参阅下图：
真的不知道它从何而来。请指出哪里出了问题。我正在使用Windows10和PDFLaTeX...
尽管我还没有使用过该hyperref包，但这个问题还是出现了，并且MWE是：
\documentclass{book}
\usepackage[T1]{fontenc}
\usepackage{times,amsthm,amsfonts,amssymb,array}%
%\usepackage{pifont}
\usepackage{tikz,tikz-qtree}
\usepackage{cgloss4e,gb4e}%
\usepackage{tipa}

\textbf{1{{sg}}.{{abs}}}-\, \hspace*{1.5pt}{{dir}}- three{{sg}}.{{erg}}- bring {-{{pst}}}\\
\glt `He/She brought \textbf{me (direct object)}.' \label{qedo}
\ex \gll \textbf{s\textipa{@}}- {qe-} \d{k}\textipa{\super w} a -\textipa{K}\\

刚才发现这个问题是由于\gll和引起的\glt，但不知道如何解决，请提出建议...
