@Bluebeat Hi Marc, I’m testing a fix at the moment which I hope will be good to go soon. The main problem is that this kind of change can have unintended consequences, so I need to do enough due diligence to make sure that it’s okay; it’s a bit like battling a hydra: solve one problem and another one rears it’s head!
Please note though that this will not fix the “Masada Guitars” track grouping, which is displaying precisely as our metadata provider intended, i.e. as a multi-part work. For this, you can use the new editing functionality that was added in the latest Roon 1.3 release. I’ve added some instructions to Michel Timmerman’s thread here.
