How come the Orthographic Camera affect the Face Liquify effect?


I've added the Face Liquify effect and positioned the two circles. Everything looks good so far. But now, when I add a "Screen Image", the Orthographic Camera shows up in my objects panel and now, when I go to my Face Liquify effect, the two circles is far away from the face template in the scene.

How come?

When I go to the 3D Scene window, it seems like the Face Liquify effect belongs to the right camera. And the Face-grid belongs to the left camera.

I've attached a screenshot here:
