Help Gigabyte Z170x Gaming G1 Wifi antenna socket problem

[japzmvh]

I just recently bought this motherboard from amazon japan for 24800 JPY(220USD). This is Brand new and all of them are packed properly and sealed. All is working properly but I noticed something about the antenna socket on the mobo itself. they are not the same. I can fit the other antenna but the other one won't fit cause there's something inside of the socket and I cant remove it.

Sorry about the photo

Can you indicate which port you can hook the antenna to? It looks to me like the port on the right accepts the antenna while the right doesn't, correct? Might be worth a closer shot of the antennas themselves and the ports as well.

The right side is the problem. there's a gold little ring inside the wifi socket.
