Villagers Randomly Disappearing on MC Bedrock Android

Villagers and even an iron golem keep disappearing every world I load up. No, they don't die from hostile mobs or wander off the village because of a lack of bells or beds, when I quit the game and go back on the world, one or two villagers just randomly disappear. Some also disappeared when I die underground, and then my villagers who I lvled up through trading just disappeared. I ended up creating so many worlds and finding villages but this issue just keeps happening over and over again. (Note that Villagers even the ones with jobs also disappear during daytime, so please fix it!)
