All my Mobs/pets suddenly dissapering

Hi, I was playing my 1.17 survival world, when I left my base around 200 blacks to the north. Within my base, I had several mobs such as iron Golems, wolves, cats and villagers. When I got back to my base around 10 min later every signal mob within my base had suddenly disappeared. All these mobs were named with a name tag and my villagers were sitting in minecarts. The minecarts also vanished when I got back.
