How to translate the field values of a custom fiel

Hi Nicolas, I am trying to translate the field values of a custom field that I use in a filter.

I open the custom field with faland and this appear:

as you can see I translated the field values and saved.

But now when I go to the page with the filter and select the English languaje the checkbox and the field values disappear.

Is the format that I use to the field values translation correct?

If I copy the original values for the field values (spanish) and save it works. But in this case, obviously, the field values appear en spanish when I choose English.

Many Thanks,

It works, Well done.

Many, many thanks for your quickly answer.
