Incorrect field textures in Persona 5 Royal?

[Neoia]

So I bought the Steam release for Persona 5 Royal about a month ago. I've been teaching myself and learning different things and today I decided that I would rip Shujin's nurse's office (F002_016_0.GFS), where Maruki is at. I ripped and fixed the textures of all his models since they weren't easily accessible and now I want to fix the nurse's office. I imported it into Blender and...

What the hell is going on?

I opened it in GFD Studio as well and was met with the same sight. When I went to look into the textures in the file to see if I could export them, every single one was just this small checkerboard.

I'm aware there is a Persona modding community. However, that community is focused on MAKING mods. I, meanwhile, am ripping this stuff for my own personal use. I wish I could ask them and the Discord, but asking modding questions when you aren't making a mod or having trouble with a mod isn't allowed. I ripped all the files that had this field's name (.FBN, .SHT, .ACB, and the .GFS model) but I have no clue how to open them if they're even remotely useful.

Are the actual textures for this field model hiding in another package for the game? I've seen successful rips of other rooms in the game and I've tried looking around to see if there was an answer to this question.
