Some Pillager see me with Potion of Invisibility

1. I used a "Potion of Invisibility" without wearing an armor or something else.

2. Some Pillager can not see me and ignore me.

3. But some Pillager recognize me although I am invisible and shoot at me.

4. The german minecraft-wiki says: "Monsters behave neutrally as long as the player is not wearing armor"

5. The english version says: "Mobs can detect and track the player only at close range"

6. The range was the same for both Pillager, one recognized me and one ignored me.
