GlowESP Help

Hi guys so I am making my own little private GlowESP (Not source code making it from scratch) Now the problem I am having is
1. the glow of the health when shooting the enemy instead of only highlighting the player model with the health it is a huge box underneath the enemy.

2. pretty sure its just what the new update does but when I am away from the enemy the esp doesn't show their correct position until closer to them (again pretty sure its what valve has added)

Can anyone help me please?

if your experiencing a glow around a player but he isn't actually there. use the IsDormant to check for the. If i am wrong feel free to correct me as i am also semi-new to this scene
