Pre-boil Volume was over 1g higher than Beersmith anticipated.

I recently reviewed http://www.beersmith.com/forum/index.php/topic,5140.0.html and setup an equipment profile for my Blichmann 15g kettle and 10gal Igloo Mash tun. I started with the defaults of 1.25g loss to trub & chiller, 1.5g boiloff and .80 gal lauter tun deadspace. I ended up way high on preboil volume so I did a dry run on my mashtun and kettle and found my mashtun deadspace was more like .5g and my brewkettle left .2g when draining just water, so I set it to .25g allowing for extra to be lost to hoptrub (I use pellet not cone mostly).

Last week I did my second brew after making those adjustments of a blonde ale as shown below

I used the exact water measurements for my mash in, mash out and sparge volumes and when I had finished collecting first and second runnings I had 9.25 gal in the brew kettle. 10gal of water for a 9.75lb grain bill seemed way to high for me, but I figured I'd trust Beersmiths output.

My 60 min boil only boiled off 1.25g instead of the 1.5 I thought I'd have, but I still ended up with over 7 gallons of wort going into my fermenters when I expected less than 6.

Do I have something setup improperly in my equipment profile, recipe or mash profile (I left it untouched at default settings)?

I just finally got Beersmith 2 so take this with a grain of salt, but I noticed in the recipe the efficiency is slightly different than what is in the setup. I don't know if that would affect volume to that extent.
 
You also have instructions to add 14qts up top then 12 qts down below for the mash-in. Which did you follow?

The 12qt is what's listed in the default light body single infusion mash profile. I used the 14qt figure provided at the recipe which I believe takes the mas profile and adjusts it by the grainbill & equipment profile..
