[NTG-context] empty page after columnset

I’m still working at the current context journal. A few articles use 2 columns in a columnset, and sometimes there’s an empty page after it that I can’t get rid of – except by a different order of articles so that those in columns end on a right page. My impression is that columnsets always "fill up" to a right page. Is this intentional? If yes, can I change it? If it’s not intentional I’ll make an MWE. Hraban
