Problems Ripping Multi-CD sets

I’m a new Roon user, installed my Nucleus yesterday. I listen primarily to classical and have ripped a few multi CD sets as an initial experiment. What’s happened is that the first CD appears as a separate album with all information displayed correctly but CD’s two, three, etc… appear as separate albums with no information found about the composer, works, movements, etc…

Any hints as to what I should be doing differently?

Try the Merge function to consolidate the separate albums into a boxset.
