slab looks off in 3D view

Hi. I have a 14" CIP two-way slab modeled in RAM Structural. At column locations, the slab is 22" thick. When looking at 3D view, one area looks off. See below. I tried deleting the 22" deck assignment and remodeling it, but that did not help. Also, I am doing the exact thing at other column locations, but I don't see the same issues there. Any ideas what might be causing this?
