thank you for your quick response.
I noticed a typo in my original script
I think I had previously tried your solution.
Note, here by mapping the DD stream (and swapping with the DTS) I still get
the error.  If I map the DTS stream twice  I get the core twice.  So your
observation is correct, it is applying the filter to both audio streams.  I
can't seem to specify this filter to just one stream.

ffmpeg -i x.mkv -map 0:0 -map 0:2 -map 0:1 -map 0:3 -c:v copy -c:a:2 copy
-bsf:a dca_core -c:a:1 copy -c:s copy output.mkv
