Bug: Holograms visually persist for players after reload

### In which plugin has the error occurred?

FancyHolograms

### What happened?

After running /fancyholograms reload, all existing holograms visually appear again for players, on top of the ones they were already seeing. This creates a “ghosted” or overlapping effect.

Steps to Reproduce:

1. Have some holograms already spawned.
2. Run /fancyholograms reload.
3. Players see each hologram twice (visually), even though the server only has one instance of each.
4. Leaving and re-entering the area fixes the visual issue.

Expected Behavior:
Reloading the plugin should properly hide and respawn holograms so that each player sees only one instance.

Observed Behavior:
All holograms appear visually on top of themselves after reload until the player leaves and returns.
