在 \caption 内使用 biblatex-chicago \autocite 不会产生脚注

Question

使用biblatex-chicago包生成注释和参考书目样式的芝加哥引用符号。由于某种原因，出现了脚注标记，但脚注文本实际上并未出现在页脚下方：

LaTeX 来源：

\documentclass[12pt] {article}
\usepackage[margin=1in]{geometry}
\usepackage{graphicx}
\usepackage[american]{babel}
\usepackage[autostyle,strict=true,threshold=1]{csquotes}

% ... removed irrelevant preamble

\addbibresource{sources.bib}
\begin{document}

\section{American Intelligence and the Cuban Missile Crisis}

The lack of reliable and accurate intelligence by the Americans caused the Cuban Missile Crisis.
Perhaps if they anticipated or had definitive proof of offensive Soviet weapons they could have avoided the crisis.
There was a failure of SIGINT, low signal-to-noise HUMINT ratio, and perhaps common sense that contributed to the Cuban Missile Crisis.
That being said, the Director of Central Intelligence John McCone focused on the possibility of offensive missiles despite the lack of hard evidence.\textsuperscript{\textbf{[TODO: VIEW CITED SOURCE 12 ON PAGE 312]}}
It is interesting that McCone was an army of one among his colleagues.
No one seemed to understand the likelihood of the Soviets establishing MRBMs and IRBMs on America's doorstep.

它为什么消失了？我可以随意摆弄和\footnotetext，\footnotemark但即使不是论文中第一次出现，它也无法为我提供Ibid. 1引用来源的自动和简写版本。

我发现了错误吗？

Answer 1

您的示例既不完整也不简洁，所以我无法编译它。但是您的问题应该可以通过添加\usepackage{ftnxtra}序言来解决。
