I'm guessing this is probably the case for the JP version as well so you may need to forward it to the JP team, but the "Record of the generals' foray" has a description that doesn't match the cutscene it is supposed to describe.

It reads: "This recording depicts August and his eleven generals pitted in a momentous struggle against a winged beast. Swirling storms and booming thunder are etched into the plate."

However, it doesn't depict August or eleven generals, and they aren't engaging a winged beast with swirling storms and booming thunder (AKA Hurkan or another waktza). It shows a handful of generals about to engage the Xol named Ashrakk.

The other key items in this quest actually describe the cutscenes from which they are obtained, so I don't see why this one should describe something different that we never see happen.
