try changing your ~/.config/kxkbrc:

[Layout]
# ... 
Options=caps:ctrl_modifier
# ...

that's the file KDE's keyboard settings change.

Also:

• caps:ctrl_modifier means "Make Caps Lock act as an additional Ctrl modifier, but keep identifying as Caps Lock"
• ctrl:nocaps means Ctrl position -> "Caps Lock as Ctrl"
• ctrl:swapcaps means Ctrl position -> "Swap Ctrl and Caps Lock"
