Hi, I've just found a graphic bug, it isn't a thing that can be dangerous or something similiar, but when I saw it, I felt bad (just kidding don't worry). So the bug is that the new advancements alert is NOT aligned in the top-right corner of the GUI. However, this happens only if the player has already completed another advancement. In my case, when I killed a sheep (that allowed me to unlock the adventure tab) the alert appeared in the top-right corner, but when I made a crafting table, its position was that you can see in the attachment. Hope this can be useful. Good day.
