Urianger Wrong Weapon display during Endwalker MSQ

During the Endwalker MSQ, Strange Bedfellows, Urianger can be see during the cutscene and outside the cutscene at Tertium (on the back train cart) with a Grimoire on him in stead of his Astro weapon. Immediately following, in a cutscene and as an interactable NPC on the open world he has his Astro weapon back.

I did not think to grab a screen shot on the open world but I have a screen shot during the CS. Just not sure how to post it here.

I'm sure a replay or even a video on YouTube has the footage for this quest.
