Placing the -D parameter between the -r parameter and the frequency list causes a warning.
Moving it to just before the -r parameter sloves this.
Not sure how 'specific' the position of this -D parameter (or others) is.
See these two examples:

But maybe the example in the README is the required sequence of parameters.
