The seed picker in 1.18 is outdated and doesn't reflect on the new world gen, since the seed picker provides outdated seed selection to the player since it showcases the old world generation. This needs to be updated so it is relevant to the new world generation changes in 1.18.

This issue is more specifically to 1.18 however, which completely changed the world generation. This is more of the seed selection being entirely outdated, not just screenshots.
We're hoping to update the seed picker soon, and you can suggest any seeds you have found in the 1.18.0.24 Beta and onwards here: https://aka.ms/MCSeedPicker

I noticed that several seeds in 1.17.40 have been removed but they are still perfectly valid; for example -513070979 for "Ocean Monuments Ahead" still generates several ocean monuments around the spawn point.
1.18 is in beta. The seed picker connects to Mojang's servers to get data. The data has not been changed because the seeds would be wrong for people on 1.17.
