Camera logic does'nt work when i add overlay collection(upbge3.0)

when i add overlay collection,the camera that i added on overlay collection can not work,
Is there any way to make it work?

There’s a button in overlay camera tab named “Overlay mouse control” to do mouse events detection with overlay camera (for mouse over/mouse over any… sensors)


thank you very much,oh can the camera be the child cause everytime i hit play the it does’nt work?
