OK, I see the issue, it’s the name taken by the track group is wrong. This thread: Grouping tracks into a single composition has some info, it appears that tags play a part here, but it’s on Qobuz and tagging the file yourself isn’t an option. Might be one to put down to bad metadata, perhaps it’s mis-tagged on Qobuz, or an AllMusic metadata error?
FWIW this KB article gives some more tagging info: https://help.roonlabs.com/portal/en/kb/articles/file-tag-best-practice but that’s not going to help you here. Just for some context.
