I cant replicate the errors.
Do you possibly have WB or Investigator also loaded?
The Calendar thing is CoreRPG functionality. I dont know if I want to go in and change that just yet. Perhaps will see how many people request that.
Let me just clarify some things.
World Builder must be made by the GM and shared by the GM. Players can only see it if its been shared to them. Players can only see the two player fields. Only Players will have the Edit Button. Only the GM will have the send to Chat button.
Investigator should be made by PCs (though the GM can make clues if they really want). PCs decide to share (make public) or not. Players can only see their own Clues and Public Clues. Only Players will have the Edit Button. Players and GM will have the send to Chat button.
Dear Diary requires the GM to activate - even just be double clicking - the date. Players can view any active date. Players can only see the player field. Only Players will have the Edit Button. Players and GM will have the send to Chat button.
Can you confirm?
