2.0.50 Water calculation issue

I just upgraded my BS2.0 to build 50 and now notice a weird water calculation.  I'm not sure if it is a bug or something I'm doing wrong....

I have my batch size at 10.5 gallons.  I'm using the same equipment profile that I've used for the last 4 years.  All of the numbers appear correctly.

When I click on "WAter Volumes" it states that I need 16.79 Gallons of total water.  No problem.  However, when I look at the "Total Mash WAter" it states that I need 6847.92 gallons of water.  Then I'm supposed to use -6831.13 gallons of Sparge water!!

Any ideas?

Thanks,
  The quickest way to correct this one is to email a sample recipe to me with the problem so I can look at it with the debugger.  My email is beersmith at my beersmith.com domain name.
