Addons remove tokens

I have tested this in several separate games.  Creating a game with Dungeon of the Mad Mage imports the tokens into the game where they should be on the maps.  However, any time I attempt to add the Mad Mage decks addon into an instance of the game, all the tokens are deleted across every map except the token page.  Help?

Hello Jeremy B., If you have loaded the Waterdeep: Dungeon of the Mad Mage module, you do not need to use the  Waterdeep: Dungeon of the Mad Mage (Map & Card Deck Addon) . From the 'Waterdeep: Dungeon of the Mad Mage (Map & Card Deck Addon)' text:  Important Notice: The  Waterdeep: Dungeon of the Mad Mage  - Map & Card Deck Addon is not designed to be added into the core Dungeon of the Mad Mage adventure module, as these elements already exist within the module. Attempting to import them into the core module will result in your current maps being overwritten by the addon's maps. We hope this information helps. Let us know if you have any further questions.
