Inconsistencies in json files

I was editing the Slovak translation and found several inconsistencies in en-US.json and subsequently in other language *.json files.

  • in the “movie” section: {
    &movie.extra(0) and it should be &movie.extra(1)
    &movie.screenratio(0) and it should be &movie.screenratio(1)
    &movie.region(0) and it should be &movie.region(1)
    &movie.subtitle(0) and it should be &movie.subtitle(1)
    &movie.audiotrack(0) and it should be &movie.audiotrack(1)
    &movie.studio(0) and it should be &movie.studio(1)
    &movie.genre(0) and it should be &movie.genre(1)
    &tags(0) - and it should be &movie.tags(1)

  • in the “book” section: {
    &book.extra(0)and it should be &book.extra(1)
    &tags(0) - and it should be &book.tags(1)

  • in the “comic” section: {
    &tags(0) - and it should be &comic.tags(1)

  • in the “game” section: {
    &tags(0) - and it should be &game.tags(1)

Sorry, I have no idea what you are referring to.
Where do you see this and why do you think it is wrong?

extra(0) means the plural version of the word
extra(1) means the singular version of the word

We deliberately use the plural version for some fields (Genres, Extras, Tags) in some places.

In Manage Pick Lists, all items are in the singular, except for the ones I mentioned.
I thought it should be unified, but if this is intentional…

This is intentional
