Consider the following MWE:

\definefloat[combination][figure]
\setupcaptions[
  number=no, %<- comment and table appears
  align=flushright]
\starttext
\startplacecombination[title=Combination]
  \startfloatcombination
    \startplacetable%[title=Table] %<- uncomment and table appears
      \bTABLE \bTR \bTD Cell \eTD \eTR \eTABLE
    \stopplacetable
  \stopfloatcombination
\stopplacecombination
\stoptext

In the latest LMTX version of ConTeXt, the table is not shown. (In MKIV it is present.) Either commenting line 3 or activating the table title in line 8 makes the table appear.

Also, once the captions appear, they don't align on the right side. When changing the caption alignment to "align=flushleft", they align perfectly on the left side.

Am I doing something wrong?

Cheers,
