Do you have PvP toggle nametags enabled?
Also do you use TAB?

I do use TAB yes, and i am unsure on the first question so i doubt it.

Tagged In Combat:
Enabled: true
Time: 10
NameTag Prefix: '&4&lCombat &c'

Currently only on premium version and when using the TAB plugin

NameTag Suffix: ''
Glowing: true

Symbol to use for the bar and how many times to repeat it. Other symbols ▊,▮,▯,|

Action Bar:
Enabled: true
# You can use any PlaceholderAPI placeholders here
Message: '&b&lCombat &a&c &e&l &b[sec]'
Symbol: ▊
Total Bars: 20
Boss Bar:
Enabled: true
# You can use any PlaceholderAPI placeholders here
Message: '&8&l[&c&lIn Combat&8&l] &e&l seconds'
# See here for bar color options - https://hub.spigotmc.org/javadocs/spigot/org/bukkit/boss/BarColor.html
BarColor: RED
# See here for bar style options - https://hub.spigotmc.org/javadocs/spigot/org/bukkit/boss/BarStyle.html
BarStyle: SOLID
Self Tag: false
Untag Enemy: false
EnderPearl:
# Time in seconds before the player can throw another enderpearl
Cooldown: 10
# If enabled, will retag the player when they throw an enderpearl
Renew Tag: true
Block:
EnderPearls: true
ChorusFruits: true
Teleport: true
Place Blocks: false
Break Blocks: false
Interact:
Enabled: false
# List of materials to block interaction, adding DOOR means all materials that end with DOOR like IRON_DOOR and so on
# Also blocks physical interactions, having PRESSURE_PLATE also allows blocking the activation of pressure plates
List:
- 'DOOR'
- 'BUTTON'
- 'BED'
Elytra: false
Eat: false
Totem of Undying: false
Open Inventory: false
Commands:
Enabled: true
Whitelist: true

Setting NameTag Prefix: '&4&lCombat &c' to empty like NameTag Prefix: '' should fix it then.
You probably aren't seeing the nametags change anyway since TAB blocks it

Thank you, ill let yk if it works.

Update: It''s completely fine now appreciate the help.
