Here is a screen shot of the basement floor plan with the lally columns shown in red the triple stud in yellow. Forgive the crude drawing...it was made using Visio with rough dimensions.

I believe the beam is a 2x10 and the joists are 2x8 (working from memory here). If you look at the diagram from left to right, at the first post the floor is only about 1/4" too high and at the triple stud it is only about 1/4" too high. The floor is about 7/8" too high at the lally column in the middle of the wall. My uniformed theory is that either the middle lally column is too high or the beam is crown up. As I write this, I wish I could put a level on the bottom of the joists/ledger board on the beam and measure the height of each column (unfortunately this is a vacation home that I am only working on during the weekend).

That is a pretty good diagram. I am going to guess that there is a continuous beam that spans left to right across both lally columns and is supported on the right by the triple stud. This would make sense, but it is likely bigger than a 2x10. I am also going to guess that the "wall" is non-load bearing, and is there acting as a partition. But you will need to verify all of this of course.

Possibly the lally columns are too tall, not uncommon. Best to check this using a tight string along the bottom of the beam, or a laser, or a level. If the lally column is too tall, it may be possible to jack it down if it has a screw, or replace it with a properly sized column. You have to do something like that very slowly, or you will crack your beam and your floor. But when you see what you have, further thinking is in order.
