Suffix "Of the Chemist" is not showing up as a filter option

Hey guys.

Specifically "Reduced charges per use"

Anyone noticed this?

I tried the process of elimination using the "Not" function and it seems the suffix is not included in the search results. (but listed in your trades just not searchable)

of the Apprentice 1 0(15–17)% reduced Charges per use
of the Practitioner 14 0(18–20)% reduced Charges per use
of the Mixologist 34 0(21–23)% reduced Charges per use
of the Distiller 49 0(24–26)% reduced Charges per use
of the Brewer 64 0(27–29)% reduced Charges per use
of the Chemist 83 0(30–32)% reduced Charges per use
