Water will sometimes appear in the bucket but it won't actually be in the bucket

 Sometimes when you place water down and pick it back up it will still be on the ground but the bucket will look like and show up as a water bucket. But when you go to place it back down again nothing happens and there is no water.  I'm going to put a link to my video because I can't put the attachment. https://youtu.be/LkQFdqqacSA
