How to add credits printed in other languages?

I am sure a question like this has been posted before, but can't find suitable English equivalents for these Spanish credits of a song (on a Mexican pressing):

- Direccion (literal translation: Direction, but does not seem to apply in this context, perhaps "Arranged by", although that's equivalent to "Arreglos")
- Director Ejecutivo (literal translation: Executive Director, not quite Executive Producer)
- Realizador (I think Producer is a good equivalent)

And do the original Spanish credits need to be mentioned in brackets? I see that a lot on the database, such "Featuring [Duo Con]" (means Duet With).

I would add the spanish listing as on release (e.g. "Featuring [Duo Con]").
As far as I know this is not mandatory, but helps other s to decide if the entry is right.

Just for the sake of being safe, I added the original Spanish credits in brackets, but I am not 100% sure I used the correct English equivalents, and that's what I was trying to figure out with this post.
This is a release I submitted and that had similar credits in Spanish:

... you can found on it many translations (spanish / english / spanish) of credit words.

I had seen that, but my credits are not there. I guess I have to reply to that thread. Thx

Director Ejecutivo

Directed By [Executive Director] (Use only for music)

Hi cdremixcollector my opinion:
First, could you add a picture with the credits, please?
For "Dirigido, Realizado" I'd select: Producer [Dirigido, Realizado] or
For "Dirigido Y Realizado" I'd select: Producer [Dirigido Y Realizado]... It depends on the way the credits are printed.
I think both are production credit roles.
About "Director ejecutivo", perhabs Executive-Producer [Dirección Ejecutiva] as on release but you can ask some mexican like matracas
Or perhaps the MusicNutter advise: Directed By [Executive Director]

Thanks for the follow up.
The credits for the songs are printed like this:

Song #1: La Muy Muy
Amanda Lalena Escalante Pimentel (Letra)
Lino Nava (Direccion, Director Ejecutivo, Musica, Realizador)
Miguel Angel Andrade Melendez (Musica)
Sacha Triujeqye (Direccion, Musica, Realizador)

You can see how I credited them here:

The credits for Music vary by track, but the credits for the rest of roles are the same for all tracks
