Porch Beam at different elevations?

[lgswe]

I have three railing walls (rails with post to beam). All are part of and open porch and screened porck. I've looked over and compared the specs. for the walls in question and they are the same for all three, yet one beam is higher then the other two (attachment). Any ideas without sending the zip. plan to Dropbox?

What control the height of the beam off the floor. I thought it would be the ceiling height, but I changed that and the beam's elevation stayed unchanged.

Beam size? check the beam size in the rails DBX. just thinking.

They all check out the same. I got tired of trying to figure it out for now. All the beam sizes were set the same to 9 1/4". There were two railing walls that the beams were higher (in elevation only--the beams were the same size. I just increased the depth of the two beams so the beam bottoms came to the same elevations as the bottom of rest of the beams. When I have more time I'll put a little more thought into it.
