Sanity check, Use my calculator to get this all correct first, then you can setup beersmith.

Not sure how I missed it last reply, but while your listed measurements are consistent with each other, the variables used to calculate them are not. There's no way to get a total water needed of 10.75 gallons from 6 gal batch size, 0.625 kettle loss, 0.125 mashtun loss, 90 min boil, 1.69 gal/hour, and 0.0874 gal/lb absorption rate. That would give 10.22 gallons total (not 10.75 gallons).

Note I found a bug just now in my boil off rate, it's treating it as a cold volume during the total water needed calculation, then treating it as a boil volume during the boil. So total water needed is about 0.10 gallons low atm, sending a patch through in a bit.
I think there's some information that's incorrect, setting beersmith aside. (check your BS equipment profiles "cooling shrinkage" setting, it should be 4.0-4.4%.)
