I saw a villager floating away from me at night in sleeping position and not dying when hit

I noticed a villager floating while flying around in creative mode. I went close to it took pics of it when suddenly it started flying away from me and vanished within seconds from view, I went and broke its bed and saw it appear in front of me. I saw some empty beds and broke them and saw the same thing happen. I then saw villagers flying in a different direction I then took pics of them to. I then thought of reporting it. Pls check into this problem and fix it.
