Default Beer Smith - Lost to Trub and Chiller

Cuerrently my new keggle does not have a diptube yet and I am leaving about 1.5gal behind. I know it's bad but I goose up the grain bill and hops to make up for it until I have the time to make a decent diptube/hopstopper.
However, i think the equipment profile in beer smith is throwing off my IBU and Gravity calcs.

I've noiticed that when I set my batchsize and my boil off% no matter what I put in for "lost to trub and chiller" I keep getting the same IBU's and gravity.
I don't know why.
Example:
7.5# Pils
1.25# White Wheat
1.25# Vienna
1oz tetnang 4.4% 70min
1oz ternang 2.4% 60min
1oz tetnang 2.4% 10min

77% Eff.
Batch Size 5.25GAL
Boil off 10.5%
Lost to trub and Chiller 1.5Gal
It calcs the same OG and IBU as when I keep everything the same and set the lost to field to 0.5gal.
does it assume trub and losses have zero no gravity and bitterness?

Default

With my actual preboil eff% calculated at 77% the only way I could make the beersmith OG numbers match my actual OG measurement was to leave the "Lost to trub/chiller" at 0.5gal (default) and up the batch size to 6.25 gal. So I guess I have a work around, but I just thought this was weird...
