Can't move pin number ?????

Greetings,

I am making a foot print of 289 pin chip.  After instantiating the array of pins it seems the pin number can only be moved ONCE!   After changing the text and placing the pin number inside the circular pin, it doesn't allow me to

move it again.  When I try to just select the pin number text it selects the whole pin.  

Thanks for any suggestion.
