I need inline citations in beamer. However, when I use the columns environment, the numbers of the indices appear wrong as in picture.
\documentclass[aspectratio=169]{beamer}
\setbeamertemplate{navigation symbols}{}
\setbeamertemplate{caption}[numbered]
\usepackage[style=authortitle,backend=bibtex]{biblatex}
\addbibresource{bibliography.bib}
\begin{document}
\begin{frame}{Introduction}{}
\begin{columns}
\column{0.5\textwidth}
cite1 \footnotemark
\column{0.5\textwidth}
cite2 \footnotemark
\end{columns}
\footcitetext{vine2006google}
\footcitetext{jacso2008google}
\end{frame}
\end{document}
