a couple of issues I can't solve (config vs. result)

[aliasname]

Likely Simon being the only one to solve this.

I have a setup which doesn't mix differnt folder into 1 album (mergeFolderAlbums = false), and it mostly works (99%).
Now I recently stumbled across an album which did contain all the contents from 2 folders, and I get no pattern why this happens with this one album while some otheres do work as expected.
Structure is
../music/../Fleetwood Mac/
and in there are the following 4 albums
1975 - 2004 - Fleetwood Mac {Expanded Remaster}
1975 - 2011 - Fleetwood Mac {Remaster}
1977 - 2001 - Rumours {Remaster}
1977 - 2013 - Rumours {Expanded Remaster}
and the Rumours album simply gets mixed all together into 1 album.
Doesn't matter which control point or player I use. Even within the Windows Explorer when using the MinimServer[NAS] entry I see that the 2 albums named 'Fleetwood Mac' do appear separately whereas 'Rumours' is mixed all together.

any idea? Anything from the config needed for some help? Till now MinimServer was amongst the very few which allowed me to keep differnt album versions separated from each other while not using ugly wrong albumnames or such like. But I now noticed that some albums still get combined.
