I'm trying to remove the word "Is" that is getting inserted before a list of Defined Types (Group Attribute) on the Group Finder for the phFilterControls.  I've been digging and it looks like it's coming from FilterControl() (Rock/Field/FieldType.cs) but can't seem to find where in there the word "Is" actually comes from or how I can pass filterMode = false to hide the col-md-2.

Anyone have any suggestions?
