Please post your full command line and console output.
If you only want those streams, then you could do:
ffmpeg -i anime.mkv -c:v copy -c:a copy -map 0:0 -map 0:3 output_anime.mp4
Also I think another issue in your original command line was that you
included -c:v copy, but you never added -c:a copy, which is why the
audio stream was reencoded.
