Why does the audio status screen always show 20-bit audio+ even when I have 24-bit audio?

Why does the audio status screen always show 20-bit audio+ even when I have 24-bit audio?

There is a known bug in our WFM/WVR series instruments that causes them to always report audio as being 20-bits instead of 24-bits when working with 24-bit audio. This bug is caused by the fact that these instruments ignore the extended audio data packets and therefore only see the 20-bit normal audio data packets.
