This sheet is for the Westfield Great River Bridge W-25-010,

you see the members breakdown for the different types of live load that the bridge is being evaluated under,

notice that if you can track my eyes maybe you can follow my thoughts as I'm inspecting both tables for the potential differences that exist here, wondering, where did they come from. Seems like the DL is the same, as you would expect, values for the truck loads vary as you would expect given their differences as you've seen previously. Distribution and impact factors are applied and calculated separately, resulting values are then tabled on the last two columns.
