I just noticed the labels are offset in one "Space Assignment By Cost Center" drawing and in the corresponding regular FMD Plan view. I believe there is a correlation to a large number of recent label moves I did to clean-up some labels that were not placed well for clarity.
In AutoCAD, the labels appear correctly centered. In FMD they look like the attached png. I believe this floor is the only one affected.
