Updating default exposure doesn't seem to be taken into account

Bug description

The exposure cannot be updated from the write_camera_details.py nor from the json directly.

Operating System

Windows 10

Camera_control version

camera36, commit: c82b021 (nov 19 2022, latest as of now)

Steps To Reproduce

Change exposure in write_camera_details.py
python write_camera_details.py
launch GUI
initialise camera 1 and 2

Find out that exposure has not been updated based on write_camera_details.py updates.

Anything else?

I have also tried to directly edit the JSON file and this didn't change anything.
