I'm not 100% sure, but I'm going to say that it means that the probe can't probe. For example, if you probe a wire, and then delete a section of that wire, the wire becomes broken and subsequently the probe goes gray: it cant read the data because it doesn't know the datatype. I figure in this instance, there isn't a working probe for scale names - maybe you could make one in the form of a custom probe using a scale property node to get the description? (the "name" isn't a valid property) Try putting the code in the red box into a custom probe:
