Whenever a player dies there is a chance that he will respawn with his name under his chest or legs, for some reason when this happens it also affects pvp, because it doesn't let you hit that player correctly, for example if his name appears under his legs and I try to hit him in his chest or head it doeasn't let me and I also have to be like really near him for some reason.

Steps to reproduce:
1 Have a decent amount of lag and play on Xbox one
2 Kill the player multiple times until his name doesn’t appear in the correct position

Observed results:
It doesn’t allow you to hit the player (with the bug) in the normal hitbox

Expected results:
It shouldn’t happen, when you kill a player this nametag displacement and the weird hitbox shouldn’t occure

In-game temporary solution:
1. Do the swimming animation in water (this will for some reason reestablish the hitbox and the name issue in-game, but can still happen after that player dies).
2. Sometimes by login out and login in this bug can be fixed temporarly.
3. If that player sleeps in a bed It will reestablish the gamertag once It gets out of the bed.
4. If that player glides with an elytra It will also reestablish the gamertag.

Methods that still affect players (that have the gamertag in incorrect position) in pvp:
1. You can still shoot players with any type of proyectile for some reason
2. You can still light them on fire
3. They can still be damaged by lava, tnt and mobs (and also players but you will have to aim at very weird and random spots to damage the other player)

Methods that DON'T affect players (that have the gamertag in incorrect position) in pvp:
1. If you try punching him, you will have to try to hit him in a certain angle/position so you can actually hit him for some reason (however this isn't the same case when you try hiting them with proyectiles)

This is an example of how it looks like:
