Desktop widgets don't remember settings after reboot on KDE Plasma

I have two KDE widgets on my desktop.
1 “Sticky Notes”. It moves to the upper left-hand corner of the screen after reboot.
2 “Analog Clock”. It reverts to the default size after reboot.

I tried a different sticky note app, not a KDE widget, and it also forgot its position after a reboot.
