I am working on a moba game in unity, with photon and i use world canvas to display the player life. In the edit mode, i can play without any problem, but in build exe, i can't see the world space canvas. i tried using other cameras, the only way i can see those canvases is to set a camera to render target and display the render result in a raw image. Here are the settings:

Is this an unity bug? I am using the lightweight render pipeline from unity 2018.1.3. Or am I doing something wrong?
