Occasional "translation missing" error, even though translation is present

[Mickiii]

Hi, 

I have a little issue that I am unsure how to debug / solve.

I am building an application that uses localized number formatting, and I noticed that sometimes it does not send the necessary variables to client_side_validation, but simply returns "translation missing" error. When I reload the page, it sometimes start working again, and moments later when I reload, the "translation missing" error shows once again. 

Basically I have a da.yml file with the following contents:

da:

  number:

    format:

      delimiter: .

      precision: 2

      separator: ! ','

      significant: false

      strip_insignificant_zeros: false

If I do this: I18n.t("number.format.delimiter") or I18n.t("number.format.separator") I see this behaviour, but if I request one of the other entries, i.e. precision or strip_insignifican_zeros it always works as expected. It is the same issue if I flip to my en.yml file. 

Why is this? Any ideas what to test / look for?

Thanks in advance for any help on this.
