Duplicate countdown #38

Plugin: Ezcountdown
Plugin version: 1.2.0
Minecraft version: 1.21.11
Server software: Purpur
Java version: 21
Storage type: yml (if relevant)
Reported by: Rostis

Issue:
The countdown seems to execute twice. The time ticks down in a weird way and sounds are played double. When the countdown ends and the plugin is set to run a command that I have set, it runs that command twice quickly.

Steps to reproduce:
Installed the plugin
Created a countdown with a custom name and time.
Started the countdown
The plugin runs the countdown twice about one tick after the first run.

Expected behavior:
The command should only fire once and the countdown should be more smooth as it only counts down one time at a time.

Actual behavior:
Plugin counts down twice at the same time.
