One song in folder was matched to album, the remainder song only or acoustid only even though the options is set to only match if all songs in grouping matched, the one song that was matched was matched to a single disc release which i think is a key point for why this is happening(i.e if it could only match a song to a 2 track release it would not be allowed)
One song in folder was matched to album, the remainder song only or acoustid only.
Details:Okay so the majority (all but one song) were matched Song only, or not matched at all. This means that song specific info is added/modified such as TrackArtist & Song Title but album specific info such as Album or Track No is not added or modified. But one song The Robots (3-D was matched to https://musicbrainz.org/release/1103e782-3b0e-47b9-aac6-000aa3b8c151/disc/1#bab376a3-fea9-4f3d-94b8-fefdc957dfbd and that is what has caused the problem
