Sure, I can see. 
I think, maybe because I’ve been away from Linux since 2013 and just returned, I see a lot has changed. Maybe I am dealing with it with my pre 2013 knowledge which I see won’t fit.
Mostly I did something while installing a software or so that is not supposed to be done. I’m sure it is my fault in any case. 
I remember I tried to play with Snapper… when I Installed last time fresh install, XFCE then LXQT, then KDE now, I didn’t install or touch Snapper (too complicated for me), just using TimeShift and it’s taking snapshots of the system on its own.
