Notes:
1. I encountered this issue on PS5 (deluxe ed.)
2. I was playing alone
3. I was playing as Drizzt

Steps:
1. Join campaign 1, companions of Icewind dale; Act 2, with CR 2
2. In the entrance, join the "secret door", the one that opens with a cube, where there are two duergars and a troll.
3. damage them to let the health bar appear (and to identify the individual bars)
4. let them kill you, after respawn, the bars will be frozen in the place they were before defeating you.
5. Return to Kelvin's Cairn, the bars will appear somewhere in the scenario, always visible from the player's sight (when looking at the direction).

Result:
health bars would be frozen in place, they will even load after you leave the area.

Expected Result:
All the elements related to enemies shall be restored to their original state after respawning (this is as per my perspective of loner player).
