Tagging image files based on Device Model

Hi there, I'm using Hazel to tag/rename/sort my massive photo library of 10 years.
In addition to Year and Quarter, I am wanting to tag images either "iPhone" or "Nikon" based on the device that captured the image (any model iPhone, any model Nikon). But, I'm having problems getting Hazel to evaluate the Device Make or Device Model conditions.
The test file is definitely an iPhone image. Have confirmed in mlds and exiftool that the value for Device Model is "iPhone 6" - I have tried the same with Device Make contains "Apple" and it also fails.
What am I doing wrong? I am hoping to avoid having to write a script that uses exiftool if at all possible.
