Compositions and songs not linking up properly

I’m having issues whereby some compositions are not being grouped properly in my local library. I’m wondering how can I fix this? I often edit MusicBrainz data, and wondering if I can sort this?

Take for example searching for Wild Is The Wind, produces two results. George Michael’s Symphonica is tagged with MusicBrainz id c7fd5017-7a01-46fe-a2a9-d12d86b84d5f

Another example of this is Mariah Carey’s Glitter soundtrack album, again all the albums have a MusicBrainz id but the naming is slightly different. Does Roon not use the MusicBrainz id instead of the track name?

Via MusicBrainz ids they both link up

Using Roon 1.7 (build 521)
