Capital One PPI Cheque - Question

Good Morning.

I recently had a successful claim with Capital One for PPI on a credit card.

I received a cheque in the post today for the amount agreed.

However, when I look on my statement for the credit card, I have a purchase adjustment for the same amount, but my previous balance stays the same.

I plan on cashing the cheque into my current account. Am I okay to do this, or will the amount the come off the credit card balance once the cheque has cleared.

Hope this makes sense, appreciate any assistance.
