[NTG-context] Too much space between the text and the beginning of the paragraph with the command \defineenumeration

Hi, I find that there is too much space between the text and the beginning of the paragraph. \defineenumeration[ex] [text={\sc\bf Exercice}, location=left, stopper={\bf.}] For example, I use the \topset with LuaLaTeX order. Thank you.
