V4.5 My young Ura Violetchi evolved into Shitekichi.... why???

I'm playing my 4.5 after a decade so I wanted to research everything I didn't know as a kid. This includes growth charts. I have no idea why then my Young Ura Violetchi evolved into the angry substitute teacher Shitekichi. They shouldn't be in the same family group, and I was so excited to get Adult Violetchi. On evolution, my stats were: 143 funny, 78 beauty, 405 spirituality. What went wrong???
