src/main/kotlin/org/wycliffeassociates/otter/jvm/app/ui/projectwizard/viewmodel/ProjectWizardViewModel.kt, line 204 at r1 (raw file):

    fun filterSourceLanguages(query: String): ObservableList<Language> =
        filterLanguages(query).filtered { filteredLanguages.contains(it) }

You already have a function with this name and a different signature. Two overloaded functions should in some sense "do the same thing", but here they don't.

The names are further confusing because with this PR you're starting to differentiate between an ObservableList created here by filterSourceLanguages and some other OL created by filterLanguages. However, as I trace the assignments backward, I find that that other filtered list (filteredLanguages, the one you're not calling "source") is created by the overloaded filterSourceLanguages function. Please rework the variable and function names so "source" always means the same thing.
