[BUG] Dungeon of the Mad Mage adding deck module removes all tokens from all maps

Pretty much the title when you add the Secrets and Runes Decks Module to Dungeon of the Mad Mage it Resets all maps sop that none of the monster and NPC tokens are there anymore.

From the marketplace page of the Map and Card Deck addon: 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. The addon is for people that own the physical product and just want the maps/cards to cut down on prep time.  Hopefully, if you remove the addon from your game it will return to normal.  If not, you may need to just start over.

Unfortunately I tried that and the tokens do not return.

You might be able to email Roll20 and get them to roll your game back if you have done a lot of work on it, but with all the extra users with the current situation, I expect their response time won't be that speedy.
