First off, I am a newbie.  I brewed my first 5 gal AG today, a modified clone of Heavy Seas Loose Cannon using beersmith. I got some strange gravitiy readings that confused me. Maybe someone can explain what I am doing wrong.
While mashing, preboil gravity was supposed to be 1059 but was 1044 with an end of runnings of 1036, way above the suggested 1010. Iodine test was good for conversion and my water volume collected was about perfect. I figured I would just end up with a lower ABV. I did add about 2 ounces of DME, which is all I had on hand, to try to get a few points back. So I take an OG reading before pitching to see how short I would be and it is 1059, very close to the estimated 1062.
I am confused as to why my water volumes are correct but my end of runnings
was so high. Should I have sparged again and then boiled the extra water off? Should the "calculate boil volume automatically" box in my equipment profile be checked? If it is, water volume is increased and it calls for a double sparge.  And how could I have come up short up on my preboil readings and then got very close to the estimated OG reading? The couple ounces of DME I added would not have been enough to get all the points back.

All hydrometer readings were recalculated for temp using beersmith.

Below is the recipe. I dont know how to attach Beersmith files. If this would help and someone can explain how to attach a Beersmith file, I will be happy to.

Mash Profile
 
Mash Name: Single Infusion, Full Body Total Grain Weight: 12 lbs 8.0 oz
Sparge Water: 2.03 gal Grain Temperature: 72.0 F
Sparge Temperature: 168.0 F Tun Temperature: 72.0 F
Adjust Temp for Equipment: FALSE (I forgot to check this box.  It is checked for the future)Mash PH: 5.20
Mash Steps

Sparge Step: Batch sparge with 2 steps (Drain mash tun, , 2.03gal) of 168.0 F water  (This changes to 2 sparges of 1.34 gallons when "calculate water volume automatically" is checked and the boil volume changes to 6.64 gal .I also have "equal batch sizes" checked and "batch sparge using batches that fill 50%"of tun.)[/Mash Notes: Simple single infusion mash for use with most modern well modified grains (about 95% of the time).

Obviously, I am misunderstanding the software setup and some brewing principles as well.  I am just unsure what to do.  Its fermenting nicely and I know it will be beer, but I would like to understand and use the software correctly.
Thanks
