Hi, are we talking about the Movement or the Work field?
If we can derive Movement from Title then we use that, if we cannot we use the linked MB Recording Work. Similarly, if we can derive Work from Title then we use that, if not we use MB Work (this is the Work that Mb Recording Work is part of)
So here are the Titles:
Capriccio espagnol, Op. 34: I. Alborada
Capriccio espagnol, Op. 34: II. Variazioni
Capriccio espagnol, Op. 34: III. Alborada
Capriccio espagnol, Op. 34: IV. Scena e canto gitano
Capriccio espagnol, Op. 34: V. Fandango asturiano
Overture “May Night”
Sadko, Op. 5
Suite “The Snow Maiden”: I. Introduction
Suite “The Snow Maiden”: II. Danse des oiseaux
Suite “The Snow Maiden”: III. Cortège

Suite “The Tale of Tsar Saltan”: II. Tsarina in a Barrel at Sea
Suite “The Tale of Tsar Saltan”: III. The Flight of the Bumble-bee
Suite “The Tale of Tsar Saltan”: IV. The Three Wonders
Suite “The Golden Cockerel”: I. Tsar Donon in his Palace
Suite “The Golden Cockerel”: II. Tsar Donon on Campaign
Suite “The Golden Cockerel”: III. Tsar Donon as Guest of the Queen of Shemakha
Suite “The Golden Cockerel”: IV. The Wedding and Lamentable End of Donon

Essentially we used the MusicBrainz Works Hierachy to work if a song is a movement of a work or just standalone work.
If It is a movement of work we add the Movement and Work fields (and there is also the Three Level Opera Works case). Is more complext than this but basically if the title looks like a movement and work we use this for the Movement and Work fields, if not possible we don’t use. If we can’t use we fall back to the MB Works titles. we don’t currently support Work Aliases but we already have an issue for that.
So for most tracks we could derive Movement and Work from title
But in the case of Overture “May Night”/Увертюра which itself is part of Майская ночь ( May Night , May Night) we didnt derive the work from title.
Now, Im not entirely clear why we couldnt use title Overture “May Night” as movement, it may be because its the only movement of that work on the release so I may be able to fix that.
In the case of Sadko, Op. 5 it is standalone Work so not a Movement so field is left blank

Ah I forgot this issue
So because we could not derive work from title for all tracks we fall back to using MusicBrainz for all tracks for better consistency, since we couldnt derive work from for track 6 we didnt do for any.
So probably the ultimate solution is really adding support for Work Aliases
So for the first five the Mb Work is Каприччио на испанские темы, op. 34 and since we don’t yet support Work aliases that is what we have to use.
Whereas for tracks 8-11 the Work Suite from “The Snow Maiden is the title in MusicBrainz so there is no problem.
