Output pins configured in the Overlay, not showing in Devicetree view

I have the following setup in my overlay file:

relay {
compatible = "gpio-relay";
relay1: relay_1 {
gpios = <&gpio0 9 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
label = "DC Mtr Tension UP";
};
relay2: relay_2 {
gpios = <&gpio0 10 (GPIO_ACTIVE_LOW | GPIO_PULL_UP)>;
label = "DC Mtr Tension DN";
};
};

I have created the gpio-relay.yaml and placed it in the gpio binding directory.

The project builds with no issue, and the pins appear in the DTS output, but these new pins do not show up in the devicetree overlay view.

Why is that?

Thanks,

Stephen
