Removing the enumitem package fixes the problem, but in the real life I need that package to remove the left margin. In the real document I use:
\begin{enumerate}[leftmargin=0cm]
enumitempackage with beamer, they are incompatible. – samcarter_is_at_topanswers.xyz Oct 18 '18 at 14:10\begin{enumerate}[leftmargin=0cm]– robertspierre Oct 18 '18 at 14:11leftmarginiinstead. – samcarter_is_at_topanswers.xyz Oct 18 '18 at 14:12
