RT-AC3100 - network map doesn't show connected guest or all clients

[Nodiaque]

Hello,

I'm wondering if it's normal. When I click on client list, I see 17 clients. But I have way more then that. On my manual DHCP, I have more then 26 clients that I can ping that doesn't appear in the client list. Is that a wanted behavior?

I'm using a RT-AC3100. All my iot client are connected to one of my 3 guest networks on 2.4ghz.
