WAV24 transcode shows 16bit on Aries

[syd]

Hi Everyone,
I'm just discovering the wonders of MinimServer and MinimStreamer.
I'm connecting with an Auralic Aries via Lightning DS.

I've set up a Transcode as shown in the image for ALAC and FLAC to WAV24
   

but the app still shows 16bit.
   

Is this just a display error or is the transcoding not working properly? How can I tell?

Thanks, Syd
