Mega gobblegums offline Zombies

Hi, I recently followed a tutorial to convert classic gobblegums to mega and all of them work except for the DLC 5 zombies chronicles gums. Whenever I go in-game to press the gumball machine, a white gobblegum appears for either Power Vacuum, Idle eyes or Reign drops and it says "Out of..." with the gobblegum name. Can anyone help me fix this? Or does anyone know what the problem seems to be with this? I would really appreciate it. Thank you!
