The example below is taken from the wiki article "Titles http://wiki.contextgarden.net/Titles," with pdf bookmark apparatus prepended and a second chapter added to the bodymatter. In the log, this produces the lines: backend > bookmarks > confusing level change at level 3 around '1 body' backend > bookmarks > confusing level change at level 3 around 'A appendix' backend > bookmarks > confusing level change at level 3 around 'back' That is, one message for each *matter change. What is the meaning of the message, and how can it be removed (short of disabling pdf bookmarks)? \setupinteraction[state=start] \placebookmarks[chapter, section, subsection, subsubsection] [chapter,section] \setupsectionblock[frontpart][page=] \setupsectionblock[bodypart] [page=] \setupsectionblock[backpart] [page=] \setupsectionblock[appendix] [page=] \definepagebreak[firstpagebreak][yes,header,footer,right] \setuphead[chapter][page=firstpagebreak] \setuppagenumbering[alternative=doublesided] \starttext \startfrontmatter \chapter{front} \stopfrontmatter \startbodymatter \chapter{body} \chapter{body} \stopbodymatter \startappendices \chapter{appendix} \stopappendices \startbackmatter \chapter{back} \stopbackmatter \stoptext -- Rik
