DrNeptune on "[Plugin: WP Super Cache] Preload Settings won't save after hitting update or preload"

I have a weird issue. I am trying to get preload setup and when I get my settings how I want them and hit update they pop back to how they were or default settings
Is this how its suppose to work like you get the settings how you want and hit go and it does its thing but you have to set the settings everytime?
