Notice for the conductor for the artist the name is Геннадий Николаевич Рождественский there is no English/Latin name. There is one at artist credit though (Gennady Rozhdestvensky) - so as a workaround if you were to uncheck Use Standard Artist Name instead of Name On Cover it would use artist credit name rather than artist name and that should fix at least some of them, could you give that a try please.
Whereas when we get it directly from Albunack artists have a spoecial latin-name field derived from the aliases available for the artist that we use for Romanize Name
<artist id="90595f34-e23e-4d0c-97cd-7d69b66e0727" type="Person">
<name>Геннадий Николаевич Рождественский</name>
<sort-name>Rozhdestvensky, Gennady</sort-name>
<latin-name>Gennady Rozhdestvensky</latin-name>
</artist>
So if the release in not in Albunack but the artist is (which would be the usual case) we could get the artist from Albunack replacing the one provided by MusicBrainz, riased issue https://jthink.atlassian.net/browse/SONGKONG-2889
