Indentation:
Choose no indentation, 2 spaces, or 4 spaces.

Remove null-valued properties and array items, including nested values. Already included when Remove Default Values is selected; your null-only choice is restored when it is turned off.

Cleanup also removes array items. Remove Default Values includes null removal.
