Changing Date Format

Where do you change the date format for the events?

I went to > com_jticketing > languge > en-GB > en-GB.com_jticketing.ini
changed the last line to the following:
COM_JTICKETING_DATE_FORMAT_SHOW_FJY="F j Y g:i A"
COM_JTICKETING_EVEMTPIN_BOOKING_DATE_FORMAT="F j Y"
COM_JTICKETING_EVENT_PIN_TO="To"
COM_JTICKETING_EVENTPIN_BOOKING_DATE="Booking Date"
COM_JTICKETING_DATE_FORMAT_DETAILS_EVENT="F j Y"
COM_JTICKETING_TIME_FORMAT_DETAILS_EVENT="g:i A"


Which should display the date for the events like so "Februrary 28, 2016"

However it still displays it as "28 February, 2016" on my website.


Where else is this changed?
