Bees keep leaving their hives forever

Bees in the wild keep leaving their hives after a while. Even with pollen on them, they keep flying away from their nest and with no bees anywhere near me, I have empty bee hives around my world. To watch them leave, make a flat world in creative, place a beehive, and spawn bees and flowers. Eventually they'll leave the nests forever as they wander through the void of land. This bug works in creative and in survival as I saw them leave their hives both in a flat world and in my survival only world.
