这是我之前的问题。我的目标是按照repeatindex设计的方式工作：在每个新页面的顶部重复主索引项。我之前的问题的答案适用于我最初给出的简化 MWE。但是，当我尝试在我正在处理的实际项目中实施解决方案时，包glossaries和/或一些简单的自定义命令似乎正在创建多个 LaTeX 错误。这个新的 MWE 中重现了错误：
\documentclass[10pt, paper=156mm:235mm, BCOR=12mm, headings=optiontotocandhead, headings=openany]{scrbook}
\usepackage[splitindex]{imakeidx}
\makeindex[options= -s index_style2.ist, intoc,name=A,title=\mbox{Appendix A},columns=1]

该index_style2.ist文件包含：
item_0 "\n \\small\\item ["
item_x1 "]\n \\subitem "
delim_0 "] \\Dotfill "
delim_1 " \\Dotfill "
delim_2 " \\Dotfill "
为什么现在会出现这么多的 LaTeX 错误以及如何预防它们？
