So this is normal... She does not feel secure because the cage still needs more branches and plants for her to hide in. Once it is set up correctly she should not sleep on the screen at night. They can not hear the way we can but if you are turning on lights in the room when you walk in this is going to wake her up. We want to try to avoid doing this. They really need 12 hours total darkness.
She is a bit too close to the heat fixture and does not have branches below her UVB lighting to choose to go there. With the arcadia 6% UVB you want a 8-9 inch distance between where it sits on the screen and the closest branches below it. I would ensure her heat has this distance at least as well. Thermal burns are high risk if they can get too close to the heat bulb. They turn dark when basking.
Here are my cages it will help you figure out how to set yours up.
