Why many ships have no 2026 sailings posted to book?

Has anyone tried to book 2026 on Royal Wonder of the Seas or Oasis of the Seas etc? These aren't posted online to book but Star of the Seas is? Anyone know why?

I just did a search for every ship in 2026 and 465 sailings were listed, with multiple ships.
Put in Oasis and six sailings were listed.
Wonder only has two.
