No Nether Wart and treasure chests in Nether Fortress.

In today's game, I went to the Nether to try the new updates in 20w10a. However, When I use the '/locate' to find Nether Fortress, I did not find any Nether Wart or any treasure chests. I checked 4 fortresses and it remains the same. Hope you can fix this bug in 20w11a.
