我正在编写一个只有浮点数（表格和图形）的文档，但在编译时遇到了麻烦。问题似乎出在babel包上，如以下 MWE 所证实：
\documentclass{article}
\usepackage{babel}
\begin{document}
\begin{table}
X
\end{table}
\begin{figure}
Y
\end{figure}
\end{document}
当我使用 编译此 MWE 时pdflatex，我得到的 pdf 文档只有四个撇号（似乎每个浮点数有两个撇号）。如果我删除行\usepackage{babel}，则我得到预期的 X 和 Y。我尝试了spanish和ngerman选项babel，但没有任何区别。
我正在使用 Ubuntu 20.04 附带的 TeX Live 2019 版本。
我这里遗漏了什么吗？
