Beamer 框架脚注中的 BibLatex 引用编号错误。如何更正？

在这篇 SE 文章中，其中有代码lockstep展示如何在带有列的 Beamer 页面的脚注中放入 BibLatex 引用。

如果一个 Beamer 页面中只有一个引用，它似乎运行良好。

然而，似乎存在两个问题：

(1) 当一页中有多个引用时。脚注中的数字是错误的（脚注外的数字是可以的），如编译后的 Beamer PDF 中的第 2 和第 3 帧所示。具体来说，脚注中的条目具有相同的前导数字。您能帮忙评论如何解决这个问题吗？

（2）当同一引文在不同的 Beamer 页面上被引用时，引文编号会增加。单个引文可以使用相同的编号吗？

非常感谢 ！

shell 命令运行

rm MWE1.aux MWE1.bbl MWE1.bcf MWE1.blg MWE1.log MWE1.nav MWE1.out MWE1.pdf MWE1.snm MWE1.toc MWE1.run.xml ; xelatex MWE1.tex && biber MWE1 && xelatex MWE1.tex && xelatex MWE1.tex

根据 的lockstep帖子修改的 MWE1.tex
