FEN string error

Hello, 

I have noticed an error when you try to insert a position or game.  When you try to paste the FEN from a Vote Chess game, for example, into the field, There is an error message that says undefined field.  

I realize that there is more than one type of FEN notation. Pasting the FEN into a online reader works fine, so why is there an error from FEN strings recieved from Chess.com boards FEN strings to the diagram field?

Maybe there is an error like the ability to castle in a lucena or philidor like position.
