[NTG-context] alternative=d gives "attr"

Hi, \starttext \subject{Contents} \setuplist[section][alternative=d] \placecontent \section{One} \section{Two} \stoptext while the minimal example above works nicely, my more complex project adds a "attr" in front off the section number (ie. "a"): attr a) Test one 47 attr b) Test two 51 Any idea where this "attr2 comes from, and how to get rid of it?? Second question: how can I add a separator, like this: a) Test one 47 – b) Test two 51 Thanks, Steffen
