Global Variables Not Displaying in Menus

[ParadiddlePride]

Bug report

Spigot version: <!-- put your servers spigot version here --> git-Spigot-3cb9dcb-77ca7ca (MC: 1.13.2)

RPGMenu version: <!-- put your RPGMenu version here --> v3.1-preview.1 (Bundaburg Preview)

BetonQuest version: <!-- put your BetonQuest version here --> 2.0-preview.21

Description:

Global variables are not displaying properly inside menus. They work correctly in events, but only display as text when you hover over a button. It displays as such: http://prntscr.com/mvx2cf
However, if you click the button it will fire the event, which uses the same variables: http://prntscr.com/mvx315
Here is the button from the menu:

  recipe_Coffee:
    item: menu_recipePotion
    conditions: recipeCoffeeLvl,invCheckCoffee
    text:
      - '&6Coffee'
      - '&d&lReq. Lvl&7: &f&l$lvlReqCoffee$'
      - '&fIncome &7- &a$incomeGainCoffee$'
      - '&fEXP &7- &a$expGainCoffee$'
      - '&f# in Inventory &7- &a%item.brewCoffee.amount%'
      - '&bClick to Serve this brew!'
    click: brewCheckCoffee
    close: false

And here's the events being fired upon click:

brewCheckCoffee: if brewCheckCoffee brewServeCoffee else brewFAILMessage
brewServeCoffee: run ^money $incomeGainCoffee$ ^nujobs_addexp Bartender $expGainCoffee$ ^take brewCoffee:1 ^folder brewServeMsgCoffee

Finally, here is the variables from main.yml

  lvlReqCoffee: 3
  incomeGainCoffee: 5.5
  expGainCoffee: 0.5

How to reproduce:

1. Create a menu
2. Make a global variable within main.yml
3. Use the variable on a button in your menu
