I have the following slide:
\documentclass{beamer}
\usepackage{multicol}
\begin{document}
\begin{frame}{Why does this happen?}
\begin{multicols}{2}
\begin{center}
\begin{enumerate}
\item Text
\item More text
\end{enumerate}
\end{center}
\columnbreak
\begin{center}
\begin{enumerate}
\item Text
\item More text
\end{enumerate}
\end{center}
\end{multicols}
\end{frame}
\end{document}
In the second column, the vertical spacing between the two \items is all wrong. What may be causing this problem?
