Konsole refuses to remember my window size

Every time I open Konsole it launches with a small window. I have to manually resize it to my liking every single time.
I am using the default, “Built-in” profile and I have “Remember window size” option checked in my settings. This is not an issue on my other computers that are running Neon as well so this appears to be something specific to this machine. I don’t remember ever playing with this setting so I am not sure why this is happening. How can I basically reset all Konsole settings to defaults?
