Bamboo Blocks Not in 22w45a World

I created a new world in the latest snapshot 22w45a.  I wanted to test the new bamboo blocks and new inventory organization.  When I opened the inventory, all was normal, but when I tried to find bamboo blocks, they weren't there. I tried crafting the blocks in a crafting table, but it didn't work.  

I'm not sure what I did to create this.
