Default iBrewmaster iPad Efficiency Calc Bug?

Maybe I'm missing something here. I've used iBrewmaster for 2 all grain batches.

The first was a porter...

9.5lbs Pale Malt 2 Row
8oz Black Patent Malt
8oz Choc Malt
8oz White Wheat Malt
80z Caramel Cyrstal Malt

Estimated OG 1.052 FG 1.014
Actual OG 1.058 FG 1.012
Boil Size 6.25gal
Calculated Efficiency by iBrewmaster 79% (seems reasonable)

The second was a Belgian

10.75lbs Pilsner 2Row Bel
2lbs Honey

Estimated OG 1.071 FG 1.010
Actual OG 1.070 FG 1.010
Boil Size 6.25gal
Calculated Efficiency by iBrewmaster 2%! WTF???

Is there something obvious I'm missing in the software? Obviously the efficiency isn't 2%. I'm new to the brewing software thing, but comparing the 2 batches I can't find any obvious difference.

That's a tough one. I think you should ask iBrewmaster support.

FYI, it's a bit unrelated but the efficiency calculation uses batch size not the preboil size.
