I have got the same problem.
I have added a ip-in-ip interface by the following command:

nos-tun -t /dev/tun3 -s 192.168.0.2 -d 192.168.0.1 -p 4 10.0.0.156

in the interface list I see this interface and it works fine,

tun3: flags=8050<POINTOPOINT,RUNNING,MULTICAST> mtu 1500
        inet 192.168.0.2 --> 192.168.0.1 netmask 0xffffffff
        Opened by PID 4368

but when I want to delete this interface by the "ifconfig tun3 down delete" I 
see it again in ifconfig! And I can't destroy it:

#ifconfig
tun3: flags=8050<POINTOPOINT,RUNNING,MULTICAST> mtu 1500
        Opened by PID 4368

#sudo ifconfig tun1 destroy
ifconfig: SIOCIFDESTROY: Invalid argument

It disapears only after reboot.

WBR,
