Mask: I can't apply settings with a custom shortcut

In Capture One Pro, I frequently create masks to darken or bright areas of my images. While creating a mask is quick, I always have to scroll endlessly through the dropdown menu under 'Apply Adjustments From' to 'User Styles' to select my custom style.

Now I created a custom shortcut, but when I use it, the adjustment is applied to the entire photo instead of just to the mask, as I intended.
