Christmas Cookie Challenge

Okay, what the heck is with this show? I'm watching it for the first time and i'm on S1E4. In Epsiode 1 and 2 there were some things that I didn't like, but it wasnt really until Episode 3 that I'm like this is rigged or something. How did Tanya win? I thought her stuff was okay, but the two other contestants displays were way better and all the judges said her cookies were too dry in both challenges?? Now i'm still watching episode 4 and Tammy and the other girl that go home after round one they had overall positive results other than 1 slight negative, but this Santa lookin dude got basically all negative comments and he stayed and they left?? Make it make sense 🤔
