Gradient Mask not working correctly

[chrislap]

When using the radial gradient mask and I use invert it activates the outer areas of the circle but without inverting it the inner circle mask is active. It is working the reverse way. How can I correct this?

What you can try is to reset the preferences to the default settings.

Reset Procedure:

• Close Lightroom.
• Windows: Hold down [Alt]+[Shift] while restarting Lightroom.
  Mac: Hold down [Opt]+[Shift] while restarting Lightroom.
• Overwrite the Preferences when prompted by the dialog.
• Close Lightroom.
• Restart Lightroom.

It's recommended to backup your preferences before you reset the preferences to the default settings:

Reset preferences for what?

It always worked like this (and in my opinion it is designed to work this way): radial filter selects internal area, with "Invert" checkbox selected - external area.

The only thing that needs to be fixed is Adobe documentation which states the opposite behaviour:
