Waterdeep Monsters don't add to compendium

Hi everyone, i recently bought Waterdeep dragon Heist and Icewind Dale. It's nice to have the campaign monsters add to your compendium, so you can drop them in any campaign you want. But for some reasons, my Icewind Dale Monsters are in there (like the Frost giant Skeleton), but my Waterdeep Monsters aren't (like Vajra Safahr or a walking statue of Waterdeep). Can anybody help me with this issue? It would be nice to have them in my compendium too.  Kind regards

Adding module content to the Compendium was a process that Roll20 started doing a while back. It looks like this was after Dragonheist was converted. I know they intend to add compendium content to older modules, but they have not announced any kind of timeline.

Keep in mind that while it isn't as convenient as being in the compendium, you can move them to any game you want through the Character Vault.
