I think the Progress dot on the shaft does not match up with the 1. You can turn the knob all the way down to 1 and then twist the shaft to match up if you like. It is also normal to be able to turn the knob greater than the numbers...it is kind of an odd design.
so basically you keep turning clockwise until it stops - which in my case brings it slightly to the left of 1 - and then clockwise to each numbered setting ?
