Missing audio for Trial & PSE Announcements - English Audio Only

I'm playing the global version of NGS on Steam. I noticed that when Japanese audio is enabled, the announcer audio for Trial Quests & PSE Burst actually works. The audio is in English. However, if I turn English audio back on I can no longer hear the announcer for the same events.

yeah, if this was the result of some higher-up cringing at the idea of an announcer or something, at least give us the option to turn it on or off ourselves!
