Dear list, When I have a mathmatrix inside a mathalignment the numbering using \NR[+] does not work anymore. Instead it prints "[+]" on the next line. I guess the definition of \NR from mathmatrix leaks outside. Affects both TL2017 and latest beta. MWE is below. Cheers, Henri --- \definemathmatrix [pmatrix] [left=\left(,right=\right)] \starttext \startformula \startmathalignment \NC \sigma_x \NC= \startpmatrix \NC 0 \NC 1 \NR \NC 1 \NC 0 \NR \stoppmatrix \NR[+] \NC \sigma_y \NC= \startpmatrix \NC 0 \NC -i \NR \NC i \NC 0 \NR \stoppmatrix \NR[+] \NC \sigma_z \NC= \startpmatrix \NC 1 \NC 0 \NR \NC 0 \NC -1 \NR \stoppmatrix \NR[+] \stopmathalignment \stopformula \stoptext
