I know it doesn’t help with you immediate problem but, for your information, the Local Adjustments in PhotoLab are much more comprehensive in that, not only do they contain Control Points, which are the equivalent of U-Points, they also contain a brush, an eraser, a gradient, an auto-mask and the new Control Line, which allows you to select non-circular areas and combine that with a gradient if necessary. Also, both Control Points and Control Lines now have selectivity sliders, which allow you to refine what tones are selected within a given mask.
