枚举列表的最后一项间距不正确

Question

这可能很难诊断，但有人能猜测一下为什么enumerate下面列表的最后一项可能间距很大吗？

\item white-grey, coarse to very coarse, tends to show cross-bedding relicts and often disseminated medium grained mafic/ferrigenous minerals (Fig. \ref{fig:HGfen2}a; \ref{fig:HGfen3}a,d).
\item mint green or blueish grey hue, massive matrix, sometimes occurring as veins in a paler yellow-red host (Fig. \ref{fig:HGfen1}b-c; \ref{fig:HGfen3}b-d) 
\item vermilion/scarlet red, massive or complexly folded with a different colour domain, occasionally slightly less competent and less dense (Fig. \ref{fig:HGfen1}a-b; \ref{fig:HGfen3}a; \ref{fig:HGfen3}c)
\item cream white to yellow, complex folding domains, attenuation of crystalline lenses picked out by light-dark gneiss-like colour contrast, resorption of clasts and heterogeneous grain size domains (Fig. \ref{fig:HGfenplasticity}a-b)

我扫描了论文中使用的序言和修改后的报告类，但找不到与可能干扰此处的setspace（用于设置\doublespacing正文的）包参数相关的太多信息。还有\setlength{\parindent}{2em}和\setlength{\parskip}{0.5em}设置来控制段落间距。

有任何想法吗？
