Roon Radio priority

I’m having a hard time understanding the selections made by Roon Radio, not exactly what to play next, but rather from where.
I played the album No Deal by Melanie Di Biasio (great soft jazz/pop/ female blues-album by the way). Roon Radio took over and played some music in a similar vein. A few songs in a track from Patricia Barbers A Distorsion of Love was selected.
A nice choice but why pull it from Qobuz when i have the very same song (and album) in the same resolution (24/96) on the local harddrive of the Roon Core? This happens quite often, tracks are pulled from streaming services when they are available locally.

Why is online services preferred by Roon Radio?
