EA6900 port forwarding manage

I have EA6900. and I set UPNP enable. also set user can define port forwarding.

When I open single port forwarding, there is only 3 port I opened. that's fine.

BUT.. when I try port scanning on my home IP. I can see 7 ports is open. Not BT open.

I can NOT find any page that let me close those ports. even I turn off UPNP then reboot router.

I am still not allow to manage those open port.
