PhotonNetwork.Instantiate Not buffered problem

Options
Hello, I'm currently developing a multiplayer first person shooter using Photon Unity networking Engine. But I have one problem. Whenever I try to spawn a object(with photonview) using PhotonNetwork.Instantiate, this is what happens:

Player 1 joins
Player 2 joins
Player 1 can see both player 1 and 2 but player 2 can ONLY see player2

I have tried using PhotonNetwork.Instantiate in completely different project, and it worked perfectly(I used the same code). Why isn't it working on my current project? Any ideas? Any fixes?
