Gordy:
In the US Library, the 2D Script for this object (Office Chair 03 12) does not have any code for the simple symbol you are showing in your screen shot. So I will ask the obvious: your screen shot shows multiple elements (the object tag is stacked), so is it possible that there is some other element covering the chair?
You should add a Signature to your Profile (click the Profile button near the top of this page) with your ArchiCAD version and operating system (see mine for an example) for more accurate help in this forum.
