[NTG-context] Figure. 3

All, Anyone know how to get a period after Figure in figure caption. I tried: \setupcaptions[separator=.] \starttext \placefigure [][fig:one] {Caption.} {\externalfigure[blank]} \stoptext And \let\floatcaptionsuffix=. \starttext \placefigure [][fig:one] {Caption.} {\externalfigure[blank]} \stoptext Neither worked.
