[NTG-context] Issue with math alignments

Hi, list! The following \starttext \startformula \startmathalignment \NC 0 ; \NC 0,3 ; \NC 0,33 ; \NC 0,333 ; \NC 0,3333 ; \NC \cdots \NR \NC 1 ; \NC 0,4 ; \NC 0,34 ; \NC 0,334 ; \NC 0,3334 ; \NC \cdots \NR \stopmathalignment \stopformula \stoptext stops working both in MkIV and LMTX. The latter includes the following: The file ended when scanning an argument. (text) {0,33 ; \NC 0,333 ; \NC 0,3333 ; \NC \cdots \NR \NC 1 ; \NC 0,4 ; \NC 0,34 ; \NC 0,334 ; \NC 0,3334 ; \NC \cdots \NR \stopmathalignment \stopformula \stoptext It seems ConTeXt is introducing a brace before 0,33. What should I do? Thank you in advance. Jairo :)
