RT-AC88U Lost top 4 ports

Hi,

I updated to the latest version of Asus Merlin (384.17) and lost the top 4 LAN ports, port 5-8.

When I go to Tools -> Sysinfo and scroll down to the Port list it says this :

Port VLAN Link State Last Device Seen
WAN 2 1000 Full Duplex 00:00:00:00:00:00
LAN 1 1 1000 Full Duplex ABCD
LAN 2 1 1000 Full Duplex Sony
LAN 3 1 10 Full Duplex <none>
LAN 4 1 Unplugged <none>
LAN 5 (RTK) NA Unplugged...
