realm server bug

Play Realm server with 5 friends.
To spend the day at night, some lie in bed, some leave the server and reconnect.
In this process, the server goes back to a few minutes.
The weird thing is that I, the host of the server, am alone on another server (the rolled-back server) and the rest of my friends are connected to a great server.
It feels like the same Realm server is divided into two.
My friends connect to where I am (the server that was rolled back) when I reconnected. This happened twice within minutes.
It's a server that's only been paid for a few days, and there's no structure that can cause delays or bugs. It's the first bug type I've seen, so please fix it.
