I'm surprised at the variation in shape factors at very low bandwidths and believe you are seeing the combined effect of cascading the DSP filter with the roofing filter.

I would not have expected the shape factors to vary as much as they are. They must be doing this intentionally, perhaps to avoid ringing at the narrower CW bandwidths.
