Dynamic Data Lists records are shown in English (US) rather than the default language when editing in spreadsheet view. This may occur even if the English (US) locale is disabled for the site.
1. Start a 6.2 EE bundle SP13, initializing the local default locale English (US).
2. Set locales only English UK and French available for portal and site, and English (UK) is set as default.
3. Navigate to Site Admin > Content > Dynamic Data List > Add a new list and a record in spreadsheet view.
4. Edit the record
Actual result: the translation still displays English (US) instead of English (UK).
Expected result: the translation should be the default set language English (UK).
