I setup my mesh network and it worked perfectly but now I see the SSID name twice on my laptop's available Wi-Fi networks list. The second one has the number "2" on the end. I've connected to them both they're both running at 5 GHz and I can log in to the router and tp-link through both of them.

I thought that the three modules are bought are supposed to seamlessly broadcast one single network. I don't understand why it seems to have separated?

Any help appreciated.
