Flower Forest Oddity

I’m just curious if there’s a potential bug for flower forests or if it’s just the world seed I’m playing on. I’ve gone to several flower forests throughout the world I’m on and every single one has consisted of just poppy’s and double block tall flowers and that’s it. No tulips, alliums, nothing. I figured I’d just ask in case it’s just a me issue. My world seed is: 2371191614. Thanks!
