it's a kind of bug; how about swapping the order: (page-lyr.tex)

\def\settextpagecontent#1#2#3% #2 and #3 will disappear
  {\doifelselayerdata{OTRTEXT}
     {\setbox#1\hbox to \makeupwidth
        {\startoverlay
           {\tightlayer[OTRTEXT]} % first, otherwise problems with toc
           {\normalsettextpagecontent{#1}{#2}{#3}\box#1}
         \stopoverlay}%
      \dp#1\zeropoint}%
     {\normalsettextpagecontent{#1}{#2}{#3}}}

(you really don't want to know what happens there -)
