[NTG-context] \placecontent (\placemylist) problem in last beta

Hello ConTeXist. When I create my own list of content, so there is a repetition of chapter numbers in the list of contents. Is it a bug in last minimals? In previous versions it worked OK! Thanx Jaroslav Here is my minimal example: \definelist[Ichap] \definelist[IIchap] \definecombinedlist[mylist][Ichap, IIchap][level=IIchap] \definehead[Ichap][chapter] \definehead[IIchap][section] \starttext \placemylist \Ichap{Chapter 1} \IIchap{Section 1.1} \IIchap{Section 1.2} \Ichap{Chapter 2} \IIchap{Section 2.1} \IIchap{Section 2.2} \stoptext
