Eagle lib creation - LQFP48 Pin Numbering

I have created a part in a new library and when I opt for the labeling for the pin & pad, I get P$1, P$2, etc for the pin - why not just 1, 2, 3, etc? Is there some option I have on or off that I need to switch? I have seen other parts in different libraries that have the same setup, but just show the 1, 2, 3 and not P$1.

Please assist,

Bob
