Issue with EKSource not localizating Default, Other and Subscribed Calendars

I have an issue with receiving localized version of the strings "Default", "Other" and "Subscribed Calendars" from EKSource. The strings aren't coming back as localized. I'm curious to know if we should be localizing strings that come from Apple ourselves, or if this is a bug?

What's interesting is that the strings are localized in the calendar app and the subtitles like "US holiday" and "Birthday" are coming back localized, just not "Default", "Other" and "Subscribed Calendars".
