Amethyst geode spawning at End Portal Frame room!

So, I want to speedrunning in Minecraft 1.17, with seed 376166226 (popular seed to speedrun). I enter the stronghold and founding End Portal Frame Room, but in that room, Amethyst Geode was spawning at that room. So I was so sad because I can't speedrunning again in that seed again, so PLEASE, fix that bug!
