Chosen module present but inactive To replicate the issue:

Install and enable Chosen module ->

(Apply Chosen to exposed filter)

Add .views-widget-filter-title to /config/user-interface/chosen under                 "Apply Chosen to the following elements"

Why is my chosen element present but inactive? (See picture)
The selector added to "Apply Chosen to the following elements" section would be 

.view-filters .views-exposed-form select


in order for Chosen plugin to be applied to Views exposed filter with select drop-down widget.
