To clarify, and re-reading your opening post, you have completed the KYC process, they've accepted the documents you provided and your account is marked as successfully passed them? Or is it still on process?
If it already passed their KYC, the betting history as you described should shed us some light and matched with Razer's explanation, that your account is currently being investigated following a big win on Sugar Rush.
Level 1,2 and 3 KYC have been passed. After the big win was asked to verify address + bank statements and that's what I think I'm currently waiting on.
