使用“verse”包解决子部分对齐问题

Question

我陷入了一个“新手”问题：

\renewcommand{\poemtitlefont}{\normalfont\large\itshape\centering} 

\begin{document}

\begin{showtitle}
    \titleRF
\end{showtitle}

\newpage

\tableofcontents

\include{Section1}

\include{Section1}

\include{Section2}

\end{document}

典型的“SectionX”文件：

\section*{SectionX}
\addcontentsline{toc}{section}{SectionX}

\poemtitle{Poem1}
\begin{verse}
    row1 \\
    row2
\end{verse}

除了生成之外，一切正常目录... 渲染结果没有我预期的偏移。结果如下：

Indice                       2
     Section1                3
     Subsection1             4

虽然我期待着这样的事情：

Indice                       2
     Section1                3
         Subsection1         4

诗包建议使用这个命令：

\renewcommand{\poemtoc}{subsection}%

但使用它只是“删除”子部分目录。

我面临的另一个问题是标题、索引和序言部分使用“罗马”页面符号...我尝试了几种方法，但总是发现第 1 页的背景被删除（这不是我需要的标题页）。

导致此类问题的指令是这样的：

contents={\ifnum\value{page}=1 \else \eachpageornament \thepage\fi},%

在\backgroundsetup指令中。将“1”更改为“i”或“I”会导致编译错误。
