I had changed from "false" to "true" for the value of the key "GanonQuest_Finished" in the savegame normal mode file, and somehow the language in description changed by itself from english to japanese (see screenshot below). Unfortunately, I cannot understand it, so if anyone could help translating it, that would be great. And could it be related to DLC #2 where the story could potentially start after completing this quest?
And the original text in english could be seen in this picture below (taken from my savegame master mode file).
