Inaccurate Self Weight of Concrete on Columns

Hello,

I have designed a breasting dolphin for vessels completely in Staad.pro with a concrete cap (3.5' thick) and steel pipe piles. I created the concrete slab using plate meshing and have assigned self weight to all members, but it doesn't seem like the Fy reaction forces from the self weight at the end of the pipe piles are correct. I'm getting reaction forces as low as 1 kip, but I figured the reactions should be more considering it should include the self weight from the concrete and from the pipe itself. I believe all properties have been assigned correctly. Is there a reason for this, perhaps based on geometry? Please see my attached file.
