something is not right with pillagers

I ran into a group of wandering pillagers, because there was a pillager outpost nearby. and when I got into spectator mode, they just started shooting me even when i clicked onto one of their buddies and tried to spectate them, they even shot and killed one of their buddies. I don't know if this is supposed to happen, if you want to find a fix for this, it's okay. it just doesn't seem right.
