Questionnaire does not display the correct dateformating text for “date” question type when using (es) International Spanish language.

In the es (Espanol-Internacional) language pack, the component “mod_questionnaire” and string “dateformatting” does not display the correct “standard text”. The text, “Use the day/month/year format, e.g. for March 14th, 1945:  <strong>14/3/1945</strong>” should be translated and displayed in Spanish. The text is not translated and instead is displaying the text “dateformatting” in English.

STEPS TO REPLICATE
1. Create a questionnaire in a course
2. Add a “date” question to the questionnaire.
3. Change language in course to “es” Espanol-Internacional.
4. View questionnaire.

OBSERVED BEHAVIOR:

The text “dateformatting” is displaying instead of the translated text “Use the day/month/year format, e.g. for March 14th, 1945:  <strong>14/3/1945</strong>”

EXPECTED BEHAVIOR:

The text of “Use the day/month/year format, e.g. for March 14th, 1945:  <strong>14/3/1945</strong>” should be translated and displayed in Spanish for the “date” questionnaire type.

Here are screenshots of it appearing correctly in both the
English (en_us) https://www.screencast.com/t/lt6zQ1yIE and
French (fr) https://www.screencast.com/t/P79sFyUvTXOL language packs.
