PyShark display_filter option not working in the LiveCapture() routine

I am not having any success, getting the 'display_filter' option working in the PyShark LiveCapture() routine. I am using PyShark ver:0.3.6.1 with Python ver:3.5.1

Eg.

import pyshark
capture = pyshark.LiveCapture( interface="Embedded3", display_filter="ntp" ) #<-Doesn't work
capture.sniff(packet_count=10)

print( capture[0] )
print( capture[0].ntp )
print( capture[0].ntp.reftime )
