Power Scaling not working with LO-X7

Using the mac version of the software (0.9.07)… settings are as shown below, power scaling is set in the shape properties from 10-100 (I have 10 shapes I’m test cutting trying to dial in some settings), but they all cut exactly the same.

Am I missing something obvious? Any of the power scale samples I’ve downloaded also don’t seem to scale at all… using they greyscale image setting also seems to function more like threshold - there is no gradient, just light vs dark.
