Hello @NickSnM first of all please do not be impolite with your comment. We are working hard to make the game the most updated every year and we are always checking all available information to be sure that what we are reflecting is the reality and not making up numbers or looking for unreliable sources.
As for what corresponds to the Spanish database (because you mix in your comment what corresponds to this thread with other leagues), Griezmann's signing was completed in October, so it makes no sense to keep him as Barcelona's property if he is no longer owned by this club. In the case of Willian Jose only the amount paid by Real Hispalis in this summer is missing, we will add it in the winter patch.
About the rest of the questions, do you have any official and 100% trusted source other than internet news?
Thanks for your comment, have a nice day.
