The problem lies in the \uniqueMPgraphic and \useMPgrpahic commands. There is a commented
line in each command which is the correct setting and the next line is wrong.
\def\meta_unique_page_graphic#1#2%
{\meta_begin_graphic_group{#1}%
\let\overlaystamp\overlaypagestamp
\setupMPvariables[\m_meta_page_prefix:\currentMPgraphicname][#2]% prefix is new here
% \getvalue{\??mpgraphic\m_meta_page_prefix:\currentMPgraphicname}{}%
\getvalue{\??mpgraphic\m_meta_page_prefix:#1}{}%
\meta_end_graphic_group}
\def\meta_use_graphic#1#2%
{\meta_begin_graphic_group{#1}%
\doifsomething{#2}{\setupMPvariables[\currentMPgraphicname][#2]}%
%\getvalue{\??mpgraphic\currentMPgraphicname}\empty
\getvalue{\??mpgraphic#1}\empty
\meta_end_graphic_group}
