I recently added an ATK to replace my old ATO and this is what happened to my Salinity probe readings. My ph also is not working properly I wonder if it is related.

Where is the ATK adding the top off water to in relationship to your probes? Never have your probes where the added top off water is added just in front of the probe rack/mount or it will cause this kind of result. Either move your probes or move the ATK to another location to prevent this.
My probes are in the first chamber where the water enters from the tank and the ATK is located in the return chamber they are separated by the Refugium. So that is not it.
Where is the wire for your salinity running and is it within 2" and running parallel of any other wires? What about micro bubbles getting in the probe from the drains coming from the tank??
Is the salinity of the tank where it is supposed to be?
Meaning, did you take a reading using a refractometer?
