Well, I solved this one and the solution is rather humbling.

I will post this in case anyone should ever run into similar problems.

Prior to creating the plan with three different flows (50, 100, 500). I had created a floodway plan which included encroachments.

When I created a new plan for the three flows, the encroachments were left on in the plan. Therefore my second and third profiles were being run w/ encroachments when I did not want them to be.

Simply looking at the cross sections would have solved this, but because they were not optimizing, I was simply looking at the profile views and output tables and not finding any answers.

Most of you I am sure would have figured this out long before i did.
