How do I fill in a gap within a Polar Array?

Hello, So I am new to Rhino and I attempted to copy a shape of mine as a polar array, however, it seems that I might have done something wrong as the pattern does not go all the way around as I intended and has left a gap where another piece should go. Is there any way I can fill this gap without deleting the array I just made and redoing the entire command?

nope, you would have to redo it. but, dont fret, that is done really fast, a little practice will make you sharp and even faster the next time.
