Volumio shows wrong bitdepth when streaming as dlna renderer

I’ve just started using Volumio as a dlna-renderer for Audirvana and everything works fine, but the displayed bitdapth in incorrect.
Volumio shows 32-bit, when the file is in fact 24-bit. Audirvana and my dac both show the correct 24/96.
Playing the same file directly on Volumio shows the correct 24/96.

I have the same issue with my Hifiberry Amp2 and the Digi2 Pro and don’t have any type of resampling or volume levelling active.
