Happyqueen, my girl is drinking friso gold, so far so good. It's what she was given in the hospital so I continued and her poo looks ok. Maybe your little one is not used to formula milk yet? Coz I believe it's much thicker than breast milk. Maybe you try using less powder e.g. instead of 2 scoops to 60ml of water you can add just 1.5 scoops. And ensure that the powder is fully dissolved.. If doesn't work then you might have to try another brand.
