Vindicator and Evoker captains are not spawning in Woodland Mansions.

Hello, i am playing on the current version of Minecraft, no snapshots or older versions, or anything along those lines. Anyways, Vindicators Captains and Evoker Captains are not spawning in the Woodland Mansion at all, it even says that they are supposed to in the Wiki. No change logs say that feature was removed. This is a bug.
