Such terse answers don't help anybody.
You click on the marked "Container" button, the frame settings window opens and you change the frame spacing in the top left corner (the 4 numbers inside the frame's image, just below the label "Spacing:"). And then nothing visible happens in MUI prefs? Sorry, but that is not possible. MUI changes the frame settings immediately. There
MUST be a visible reaction. You can even use Drag'n'Drop to copy over a completely different frame with different spacing of another object. Have you tried that as well?
You really need to be much more verbose. As I said before already "it doesn't work" is no sensible description/explanation of an issue.
