I posted this in Roon Software so just hitting a wider audience here.
Under 1.7, I have the following and the other versions showing nicely.
All albums identified and are fine.
Under 1.8 - none show, and from the same database just imported over.
Despite what I can do under 1.8, I cannot get other versions to show. Ugh.
+1 for having the version count available again on the multi-disc icon like it was in 1.7.
