[Mapping] Collider issue

Afternoon mappers, I’m struggling just a little with removing a door collision.

I’ve openend the following files below and removed textures and colliders. Does anyone know how i’d get around this?
dt1_23_0.obn
dt1_23_build2.odr
hi@dt1_23_0.obn

So i was successful in removing the door and the textures just not the collider although its showing in 3ds it is, I exported it to fivem and tested twice with no luck.
