Location: User tab in Support Ticket
User Field: Language

Issue:
The drop-down list to display the user languages supported is currently sorted by language in their respective languages (see screenshot below) while the language displayed first is in English (this is the language my Zendesk is set to). 

Reason:
This situation leads to confusing situations where e.g. German is currently listed between Danish and Estonian. This is confusing, time-consuming, and prone to mistakes.

Solution:
Sort the dropdownlist in the language Zendesk is set to, e.g. English.

Should you have any questions, please do let me know.
