I originally posted this as a metadata problem, but now feel it is probably a new problem introduced in Roon 2.0 and may represent a problem with handling multi-disk sets on that new release. (Remember that most users are using databases largely consisting of entries made with Roon 1.0 and that the number of new multi-disk entries made on Roon 2.0.7 is probably fairly small.)
I making this new posting to make sure my entry gets looked at from that perspective, rather than as just another random metadata problem.
See https://community.roonlabs.com/t/roon-mishandles-metadata-for-grace-jones-warm-leatherette-2016-2-cd-reissue/229486?u=peter_gettinger for the details of the problem.
