Califax, the Level 3 Keeper of the Grove, defending the cell that Illidan is in, is not named in reforged and 3 skeletons in the middle of the map are tagged as Watchers. Also one of the Ancient Watchers at the most south eastern edge of the map is labeled a creep and not part of the Watches despite the rest being labeled as a Watcher.
The blank name is related to a large data bug from 2019 - apologies for missing that.
Fortunately none of these affect the gameplay - fixes are unlikely.
