Late Additions Check Box - ALL Button?

[AHarper]

In the Late Additions Check Box section of FAQs suggests there is an ALL button that can be selected to display the changes to the OG if a fermentable is selected as Late Addition. Where is it?
Slelecting the Late Addition check box alters the IBU values and changes the Boil Gravity in the Batch Stats. Is the button now superfluous? If so the FAQ needs attention.
