"Sing Me Another Song" Japanese Text Minor Bug

When completing the quest "Sing Me Another Song" (the quest in Revenant's Toll unlocking Savage SCoB), the game's non-dialogue explanation following the Minstrel's dialogue displays in Japanese text, on the English version of the game with text display settings set to English. The same Japanese text appears in the text log window.

Nothing else seems to be different. The quest completes normally and Savage Coil becomes available, with all further text displaying as normal.

For reference, this happened when I turned in the quest shortly after the emergency maintenance and update on Oct. 30th.
