Hi-Res FLAC Conversion to Radio

I'm curious about what's going on with FLAC conversion to a SB Radio, hope someone can clear this up. In playing FLAC 24/96 (or higher), LMS is seemingly converting to 24/48 FLAC (max supported by SB Radio), per this command which I extracted from the transcoder/server logs:

[21-04-20 12:04:16.9687] Slim::Player::Song::open (567) Tokenized command: "/usr/share/squeezeboxserver/Bin/x86_64-linux/flac" -dcs --force-raw-format --sign=signed --endian=little -- - | "/usr/share/squeezeboxserver/Bin/x86_64-linux/sox" -q -t raw --encoding signed-integer -b 24 -r 96000 -c 2 -L - -t flac -r 48000 -C 0 -

This looks good so far, as I have the FLAC->FLAC conversion set to "Native" in File Types, so LMS is correctly keeping FLAC and down-sampling to 48k before delivery to Radio. Good.

However, when I check the More Info as the 24/96 track is played, I see:

Bitrate: 2486kbps VBR (Converted to 705kbps FLAC)
Sample Rate: 96.0 kHz
Sample Size: 24Bits

Can this be correct? The 2486 kbps is likely the original 24/96 bit-rate, not the 24/48 converted rate? Also, how is it that a 24/48 FLAC (after conversion) is now a "705 kbps FLAC"? That seems rather low, given that the "-C 0" (compression factor) option in the sox command above is least compression?

I'm probably just overlooking something obvious, thanks for any clarification!
