Pt shows classical signs of lack of platelet ADHESION. ADHESION is mediated by vWF. Platelet AGGREGATION studies test for AGGREGATION, which is mediated by fibrinogen, thus they have normal results on lab testing as they are not testing a pathway that uses vWF (very miniscule detail I know, very annoying).
