When I try to place a Frost Giant the token won't load.

So I am trying to add a few Frost Giants to my game for character development but when I drag the monster from the compendium onto the table the default token shows (as in the silhouette when a token is not associated). I thought I would have no problem and just started adding them before my session any help would be appreciated!

Two questions: Do you have a purchased compendium such as the Monster Manual, which includes tokens monsters? If so, do you already have a Frost Giant in your campaign? If there is an existing frost giant, whose default toke is not set, a compendium drag will only bring in a copy of your existing frost giant, with its unset token. This behavior is to prevent accidental overwrites of homebrew content. Either delete are rename any existing "Frost Giant" in your journal tab and try a fresh compendium drag. 

First I am playing Curse of Strahd so no Frost Giants. I did try to just add a Frost Giant via creating a character but I deleted it before getting the manual. Second I am trying to add them by the Monster manual which was recently purchased.

Wait I forgot about another Frost Giant Stat Block I was trying to set up but forgot to delete which may have caused the issue, thanks for explaining and helping me. I hope you have a wonderful day!

If it works, I will! :)
