Content share Issue

Good day friends,

We are facing an issue,

I am sharing books inside a campaign, Players can access all items etc, but DM cant put Monster tokens from my bought monster manual 2014 year.

And since he is DM when he launches campaign I also dont see those monsters, because it says , this monster is not in DMs library.

Please assist, we already checked our entintelments, both are synced

The DM needs his own copy of the Digital MM or he can home brew every monster he needs.
