Playing around with the zooms won’t mess up your overlay background. It’s only used to move the “camera” around the screen, it doesn’t move overlays or characters.
Also as already said, some of your characters and spots you have Jane walking to are technically not in zone 1. So when you had reset your zoom, you could only see the spotlights because as Farah said you were in the wrong zone. So if you’re in the wrong zone it’s harder to use the camera to focus on a character in a different zone so you have to cut to that zone to do it properly.
On the last bit of your script where you have Jane walking to the person behind the desk, that’s in zone 2 and therefore you need to then cut or pan to zone 2 to have the camera on her. But you currently have it left in zone 1 when you have her walk to zone 2.
I would suggest getting familiar with cutting to zones and spot directing characters while being cut in those zones you intend on having them stand in and then getting familiar with the camera tool. Cut to the correct zone they’re in and then use the camera.
