Editor startup questtion?

Ok, I’ve always wondered about this, but why do I get two racks to select from when I go through startup with the editor and my iDr 32. It’s the only rack I own and the only thing connected and yet I get what looks to be an iDr 16 sized shape and a iDr 32 size. I always select the bigger and continue with startup but have wondered why two show up. Anyone seen an explanation for this? Thanks!
