FFmpeg tee muxer processing audio differently

I'm struggling to get the tee muxer to work. When I output to a local file directly it works, but when I replace the output with a tee it fails, so:-

ffmpeg -loglevel trace -f mpegts  -i  udp://192.168.0.200:10001?fifo_size=50000000\&overrun_nonfatal  \
-map 0:v -map 0:a:0 -map 0:a:1 -map 0:a:2 -s 640x360  -c:v libx264 -b:v 600k -vbsf h264_mp4toannexb  -acodec copy   -bsf:a aac_adtstoasc -f flv test.flv

works but

ffmpeg -loglevel trace -f mpegts  -i  udp://192.168.0.200:10001?fifo_size=50000000\&overrun_nonfatal  \
    -map 0:v -map 0:a:0 -map 0:a:1 -map 0:a:2 -s 640x360  -c:v libx264 -b:v 600k -vbsf h264_mp4toannexb  -acodec copy   -bsf:a aac_adtstoasc -f tee  "[select=\'v,a:0\':f=flv:bsfs/a=aac_adtstoasc]test.flv"

doesn't.

The errors are:-

[flv @ 0x55e8ee4c19a0] Tag [15][0][0][0]/0x0000000f incompatible with output codec id '86018' ([10][0][0][0])
[tee @ 0x55e8ed34d6e0] Slave '[select='a:0':f=flv:bsfs/a=aac_adtstoasc]test.flv': error writing header: Invalid data found when processing input

I've tried to research what this means, and I think it is saying AAC-LC is not compatible with AAC. Perhaps I've got the syntax for the tee wrong, but I don't understand why -acodec copy works in one instance and not the other. I believe this is definitely on audio issue as

-tee  [select=\'v\':f=flv:bsfs/a=aac_adtstoasc]test.flv

works.

Have also tried on windows ffmpeg version N-78964-g5061579 with the same results.

Help would be most appreciated as this is driving me mad!!
