Hard time with tutorial

Options
Hi guys i hope you are all doing well !

i'm new to photon and online programming so i started with the pun 2 tutorial. I completed the step 4 and here is my problem : i connect two clients, the first one create a room, the second one join this room, they can both leave. Everything is fine BUT then when the first one click start once again to create / join a room, and the second client try to join, the second enter room for 2(which is normal) but the first one stay in room for 1. My first client is my unity editor and when the second join i have two "Room for 2(is loading)" created in my hierarchy. so client one is stuck in room for 1 with two room for 2 that are trying to load. Client two is in room for 2. Then client one can't leave the room and i get this message when i click the Leave button "Operation LeaveRoom (254) not called because client is not connected or not ready yet, client state: Leaving". Client two can leave without problem.
