Unable to create new Catalog Type

I've been working on creating a series of compound cells that are unique to one of our company's largest clients.  Now that I'm ready to set them up in the datagroup system, I'm not being allowed to create a new Catalog Type for these new cells/Items.  The option to create a new type is there, but it's faded out and won't be clicked.  I've had success creating new catalog items, but not a new Type set.

I've opened the Catalog Editor both through XM while working on building models, and as a stand-alone.

Any suggestions would be great...
