Every time I plant a wheat seed, a few seconds later, it will just pop out! When I go to try again, it pops out again. I've had this problem for a while, but now this is really annoying me!!

Every time I plant a wheat seed, a few seconds later, it will just pop out! When I go to try again, it pops out again. I've had this problem for a while, but now this is really annoying me!! I tried to bresk the soil and I have fully hydrated the soil, that is why I thinks it's a bug.
