If you click on a radio button that is already filled in the Default Spacing dialog of the Flow Chart menu, the Amount boxes will update to show that the other radio button is active, but the correct radio button will not be active.
This means that the values in the Amount boxes will be correct for the unfilled button, rather than the filled button.
There are two solutions available:
1. Do not click a radio button that is already chosen.
2. Click the radio button again and it will switch back to the correct Amounts.
