My splitscreen animation keeps rendering incorrectly

[Titanicminion 175]

I am making a split screen animation where I used the surface camera texture technique and in the animation, it requires 3 cameras and 3 surfaces for the split screen, there's another camera for the surfaces to parent to and to capture the animation in general.

but here's the problem, when I play it, all 3 surfaces will play, but when I rendered it, only one of them played. which is a problem,
 

I have tried many ways to fix the problem,  I tried toggling the camera's visibility (the visible switch thing in keyframe setting,) but that just renders the animation in one of the camera's responsible for one of the surfaces.  so basically its the wrong camera. I tried resetting MI, but that didn't work either, and I tried the hide feature for the cameras but no avail.

is there a way to fix this problem?
