Rust debug doesn't show enums

I have an Enum of a Barnes-Hut Tree:

#[derive(Debug)]
pub enum BHTree<T>
where
    T: Num,
{
    Empty {
        boundary: Rectangle2D<T>,
    },

    Occupied {
        boundary: Rectangle2D<T>,
        point_mass: PointMass<T>,
    },

    Root {
        boundary: Rectangle2D<T>,
        avg_point_mass: Option<PointMass<T>>,
        nw: Option<Box<BHTree<T>>>,
        ne: Option<Box<BHTree<T>>>,
        se: Option<Box<BHTree<T>>>,
        sw: Option<Box<BHTree<T>>>,
    },
}

When debugging it only shows this:

And there is nothing below there. Why is this?

When using VSCode with the Native Debugger everything is visible.
