Hi, in setuphead, I try to get a decreasing size of the section number according to its level with \defineconversion and \definestructureconversionset. It works as expected for the first levels, but between 6th and 7th, the variation doesn't occur. Any clue about what is happening ? For the MVE, I've added a visual check in dark red to show the discrepancy. \setuppapersize[A5] \define[1]\NivA{\tfc #1} \defineconversion[NA][\NivA] \define[1]\NivB{\tfb #1} \defineconversion[NB][\NivB] \define[1]\NivC{\tfa #1} \defineconversion[NC][\NivC] \define[1]\NivD{\tf #1} \defineconversion[ND][\NivD] \define[1]\NivE{\tfx #1} \defineconversion[ND][\NivE] \definestructureconversionset [mysectionnumbers] [N,N,NA,NB,NC,ND,NE] [N] \definestructureconversionset [mysectionnumbersforlist] [N] [N] \setupheads [sectionconversionset=mysectionnumbers] \setuplist [section, subsection, subsubsection, subsubsubsection, subsubsubsubsection] [numberconversionset=mysectionnumbersforlist] \starttext \placecontent \startsection [title={Section}] \startsubsection [title={SubSection}] \startsubsubsection [title={SubSubSection}] \startsubsubsubsection [title={SubSubSubSection}] \startsubsubsubsubsection [title={SubSubSubSubSection}] \stopsubsubsubsubsection \stopsubsubsubsection \stopsubsubsection \stopsubsection \stopsection \color[darkred]{{\tfc 1.}{\tfb 1.}{\tfa 1.}{\tf 1.}{\tfx 1}} \stoptext
