It is random in terms of what charm shape slots you'll get. It's a PITA, but if you fully upgrade something and don't like the charms slots you get, you can sell it, buy a new one, and try again. I had a pair of bizarre gauntlets that had circle, triangle, triangle slots. I sold it and bought a new pair and upgraded it. Now I have circle, square, circle. :)
