[NTG-context] \startfiguretext question

Hello, I'd like to use \startfiguretext together with \startcolumnset. If I outcomment \startcolumnset, it works ok, otherwise the figure is no longer left aligned and there is a big gap between the figure and the text. Any idea? Tobias \setupcolors[state=start] \setupbackgrounds[page][background=color,backgroundcolor=gray] \definecolumnset[poster][n=2] \setupcolumnset[poster][each][background=color,backgroundcolor=white] \showframe \starttext \startcolumnset[poster] \startfiguretext[left][]{none} {\externalfigure[foo][width=2.5cm]}{str} \stopfiguretext \stopcolumnset \stoptext
