Hello! Unfortunately, this is a recent bug that we are working to fix. This only effects the Layers panel "Create new fill or adjustment layer" button. As a workaround, until we get this is addressed, you can still use:
- Layer > New Adjustment Layer > Hue/Saturation
- Adjustments panel > Single adjustments > Hue/Saturation
All three methods produce the exact same results, there is no difference between these options.
