Why does moving the camera cause some layers to move around?

Forgive me if this question has been asked before--I couldn't find it in the FAQ or by searching. Basically, I'm wondering why some of my Vector layers fly around when I move the camera while others stay put. I thought putting everything in a group layer would solve the problem but it hasn't. This is very baffling, as it's usually just one or two layers that shift around, and it hasn't happened with every new project. I'm using Anime Studio Pro 8.

Thank you.

Layers are affected by camera movements by the Z value.
When you move a layer, basically ypu move it in 2D, but if you look well, in the top, among the X and Y values, there is the Z one, that gives to layer a "3D" position on scene. It used mostly for paralasse effects.
Put it to 0 and the layer will behave right!
