I'm finding that player ratings are changing each time i click on them even after their fully scouted. Example. Let's say i click on a player's card who i've fully scouted and it says he has Exceptional Speed and Remarkable Hands. If i close that card then come back and click on it it will now say something different like Great Speed and Great Hands. Why is this changing? Is this intentional?

It's intentional and happens because there is uncertainty in the scouting. Technically we may be able to persist the scouting plan the first time you open it, and we may look at that for a future release.
