[NTG-context] bug in \definestructureconversionset[footnote] ?

Please run example below: \definestructureseparatorset [footnote][][] \definestructureconversionset[footnote][number,characters][numbers] \setupenumerations[footnote][numberconversionset=footnote,numberseparatorset=footnote] \setupfootnotes[way=bytext] \starttext test \footnote{xxxx} text test \startfootnote note \stopfootnote test \startsubfootnote subnote \stopsubfootnote test \startfootnote note \stopfootnote \stoptext How can this be fixed?
