Yup, this has to do with the data we are receiving from Qobuz, not what kind of account you have — Roon only supports streaming anyway.
The issue is that in some cases, Qobuz supports 2 different sample rates for a given piece of content - they can stream at one sample rate, but they also offer downloads at another sample rate (generally higher).
So the bug here is that for this content we are showing the sample rate for the downloads, instead of the stream.
For now, you can always trust signal path, and the sample rate values we show will update as soon as this issue is resolved.
