More than 3 values for [SearchBy] field?


I'm trying to search by 4 values, for example, artist, album, track count, and year, however Mp3tag's UI only ever shows a maximum of 3 input fields when running the web sources script, despite 4 (or more) values being defined, e.g.:


Only A-C will show, with D not displaying.

Is there a current limitation of a maximum of 3 values for [SearchBy], or how do I make this work?
