Slider can't go under 1900K

[Lanon]

The slider for setting what color to go to during the day, sunset, and at night, doesn't go under 1900K. With my current setup late at night 1900K isn't enough but 1200K is far too much but I can't set an amount in between these two numbers.

Go into the f.lux options and choose the wider slider range.
