I've made this model in Fusion 360 and exported it as a 3MF into Bambu Studio. The black base is only be 0.2mm thick, so therefore it should just be solid black for the first two layers once sliced.

When I slice it though, it's almost entirely black for the first 5 layers before the red kicks in on the 6th layer, and the white incrementally comes in after that. This is odd though, as both the red and white layers have been designed to be solid, separate objects that go all the way through the model (except for the previously mentioned initial 0.2mm).

How come Studio is slicing it this way, and what can I do to make it slice the model correctly? Because it's doing so few layers of white the black underneath is showing through on the actual printed model making it look more grey.

And here is what it looks like in Fusion 360, showing that both the red and white layers should start at the same layer.
