How does you language.def file look?

The duplicates are OK. etex.src has no support for synonyms, so the languages
are duplicated.

You can't disable languages in language-local.dat.lua: language.dat.lua controls
dynamic loading of the language, as opposed to its definition, which is
controlled by language.dat for latex-based formats and language.def for
plain-based formats (with etex.src). So I recommend you use only
langage-local.{dat,def} but leave .dat.lua empty if your goal is to disable
languages.

Did you disable the languages in language.def? Btw, this is not specific to
luatex: for pdftex too, languages are controlled by language.def for plain-based
formats.
