Describe the bug

When two or more players open a menu, it will control every single player's menu that is currently open as well.

To Reproduce
Steps to reproduce the behavior:

1. Have one player run /help
2. Have another player run /help
3. Have one of the players interact with the menu
4. Both separate players will see the menu interact the same.

Expected behavior

Menus do not affect other players menus.

Additional context

This is due to how the plugin makes the menus static, it only creates one menu to reduce load, however this seems to have caused this issue.
