KDE Config reseting to Default

I am loosing all my KDE config as soon as I unplug my laptop from the display port connected to a 27’. Other way to say it, if I use my laptop with the internal screen and then I plug the laptop back to the display port to use it on the 27’ screen, the config is reset to default.
Nothing appears to be broken. I just need to rework the config stuff and that is it.
Any ideas ?
