Dropping Summoned/animated Creature duplication issues

I have a necromancer in my game, he has the ability to Animate Dead. I have brought out a Zombie token (MM), duplicated it, closed out the original Zombo token, then have tried to drag and drop the dupe onto the map. The dupe will not move to the map, you see that it looks like it is moving but the token never shows up. I tried this in different games that I have and cannot get it to work. I have assigned permission to myself (GM) and the player and nothing for both of us. Any suggestions/help?

The reason its failing to work is because roll20 is trying to stop a permissions issue from occurring.  The default token is set to a ghost token till you change it.  Select the zombie token from the DM sheet, duplicate it on the map, take the copy, change its represents as option to the players zombie sheet, then save IT as the players zombie sheet's default token.  If you don't change what sheet the zombie is pointing at, then you will just repeat the same ghosting token issue again.  

Is this a new change? Previously I was able to make a dupe, go to the dupe assign to a player and be done with it. This adds more steps to assign a token to a player. I was finally able to get it to work, but that is more of a pain than it is worth it seems, especially if you are trying to do it during a session.
