[NTG-context] Problem with the second \HL in the matrix

Dear List, After some work I have this example. \starttext \startformula \startmathmatrix [fences=parenthesis] \VL\NR \HL \NC \NC \NC \NC \NC \NC \VL \NR \stopmathmatrix \stopformula \stoptext My problem is, that after the second \VL the \HL goes on the left side, and is too long, and not on the right side. Should be as the first one, but shorter. Many thanks Uschi
