Problem with Hijacker

But I think the problem is more with my install.
Complete newbie to Nethunter. I have installed on a Nexus 6, and most things seem to be working, but Hijacker is giving me grief.
If I run airmon-ng on my externally connected USB wifi card, and then run airodump-ng, it works fine.
However Hijacker doesn't work for me.
When I do the command test, they all fail, and when I copy the command and run it in a shell, it shows me the path to airodump (and other executables) as being in /data/user/0/com.hijacker/files/bin
That path does not exist for me.
but when I do a "which airodump-ng" I get it in /usr/sbin/

Is my chroot not done properly or something?
When I check the chroot in the Nethunter app, it gives me "everything is fine"

I'm sure I'm doing something simple wrong, but if someone has any ideas, they would be appreciated.
Thanks
