nRF52840DK SPI Issues

I was in the process of evaluating a driver when I noticed I2C communication was not working as expected.  I put a probe on the relevant pins and noticed the Voltage on my SCL pin looks like it is misconfigured or being pulled down by something.

I am using the nRF52840DK for testing and ran this without nothing attached to verify none of my wiring was the cause.  The overlay file I am using is very simple it is just:

&arduino_i2c {
	status = "okay";
	bmp585@47 {
		compatible = "bosch,bmp585";
		int-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
		status = "okay";
		reg = <0x47>;
	};

	clock-frequency = <I2C_BITRATE_STANDARD>;
};

This means that my I2C bus should be: SCL = P0.26 & SDA = P0.27.  If anyone has seen this behavior before or has any suggestions let me know.
