Kali 2.0 Fern results not populating

My setup is as follows:

Kali 2.0 running on virtual box with an Alfa AWUS036NH connected via USB in virtual box
all the latest patches and updates applied
a while ago when the switch was made from mon0 to wlan0mon for the monitoring interface
when I would run airodump-ng or wash nothing would populate until I did the following

For everyone who has problems finding networks with the airodump-ng in virtual box:
stop existing monitoring deivces
airmon-ng stop <monXY>
set the wireless adapter offline
ifconfig <wlanXY> down
get new mac
macchanger -r wlan0
the most common cause is that a connection manager is running on your system and takes the card out of monitor mode.
now let's fix the airmon-ng issue.. lets kill all connection managers (dhclient) (works only correctly if wlan0 and mon0 are offline)
airmon-ng check kill
restart
ifconfig wlan0 up
airmon-ng start wlan0
airodump-ng wlan0mon

I recently tried using Fern but got similar results where no results would populate even when I tried the above steps.
Anyone have any ideas or encounter the same issue?
