Sweet Treat Showdown Is Exhausting

I was at round 5 and I used 6 sugars for 32%. I had total 92% chances and still got a dessert disaster. No idea what am I supposed to do. I use my sugars very carefully. And yet this is what happens to me everytime I go for sweet treat showdown challenge. I've just passed 1 or barely 2 challenges in these years. You guys need to improve this issues. We bring it above 90% and still it gives us desert disaster. I humbly request you to look into this problem and solve it for us.
Thank you
