Hi PnkKate
Try not to worry about it. Some assessments are open to being checked. (They are chosen at random) It's looking at what the assessor has done against what you said and the information you provided. You shouldn't have to go through anything more. It is a standard statement they use to say they will ask you for more information if necessary.
