recipe calculator.boil size wont calc pre and post?

[Rudibrew]

hi im building a new recipe,but the pre and post boil calc button stays greyed out?

Most likely this is due to it not being saved. The calc button relies on the quick water requirements which runs via the server, so new recipes that aren't saved don't work.

I'm hoping to have this resolved in an upcoming update but not sure when it will be released.
