Getting "Label appears on" error

[TK5090]

Hello everybody,

I'm currently experimenting with MCUboot and trying to define custom flash partitions for the nucleo_g474re board. However, I'm running into a problem:

The device tree compiler throws the following error:
"devicetree error: Label 'slot0_partition' appears on /soc/flash-controller@40022000/flash@8000000/partitions/partition@8000 and on /soc/flash-controller@40022000/flash@8000000/partitions/partition@8800"

Has anyone encountered this issue before or can point me to what might be wrong in my device tree configuration?

`/ {
chosen {
zephyr,flash = &flash0;
zephyr,code-partition = &slot0_partition;
};
};

&flash0 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;

    // Bootloader erstmal auf 32kB setzen
    boot_partition: partition@0 {
        label = "mcuboot";
        reg = <0x00000000 DT_SIZE_K(32)>;
    };

    // Anwendung startet direkt nach Bootloader und ist vor dem Flash EEPROM
    // Das zwischen ist also noch ca. 464kB frei
    slot0_partition: partition@8000 {
        label = "image-0";
        reg = <0x00008000 DT_SIZE_K(464)>;
    };

    // Reservieren von 16 kB für das Flash EEPROM
    storage_partition: partition@7c000 {
        label = "storage";
        reg = <0x0007C000 DT_SIZE_K(16)>;
    };
};

};`

I thought, that my .overlay file would overwrite the existing node definitions?
