Panasonic GX7 - exposure compensation in manual mode

I have full control over Aperture and SS, have the ISO set to a value (i.e. not auto). No matter what combo of settings I get, the camera always seems to automatically increase (or more often) decrease Exposure Compensation. I can’t change the value in the menus and pushing in the back dial doesn’t work either (this usually allows me to change this in AP and SP modes).

Please can someone point out where I’m going wrong?

You've run out of parameters to change.

Exposure compensation tells the camera to produce a brighter or darker image than its light meter/assessment of the scene proposes.

In fully auto mode the camera will make use of combinations of shutter speed, aperture value and ISO to produce an image with the brightness you're requesting.

Once you've taken manual control over shutter speed, aperture value and ISO, you've taken away all the tools the camera might use to adjust the output brightness, so trying to apply exposure compensation doesn't do anything.

For some Canon models, at least, it will change the power settings of the flash if in use.

For some Nikons, at least, doesn't it bias the light meter more or less for scenes that ares consistently too light or too dark?

Myself I'd rather achieve the same by picking one of the ISO, speed or aperture parameter to play with and leave the other two where I want them.
