Tuff Bricks and Pale Oak has Vanished

I have a private server on 1.21.5, and when I updated the server I found pale oak logs missing from builds, and tuff bricks missing from trial chambers. I don’t know why this is happening, but please help out soon. If you look at the screenshot it is a trial chambers, I am in creative mode, and have not destroyed anything, but ALL the tuff bricks and other variations have vanished.
