Credit card refund appears as charge

I refunded a purchase at Canadian Tire a couple of days ago. I checked my credit card activity and to my surprise the refund immediately appeared as a charge instead of a credit.

Today the charge has fallen off and there is no sign of a refund, only the original purchase charge from a week ago. I have the customer receipt for the refund. The purchase and refund were via Apple Pay for the same credit card.

Any one else with similar experiences? Will the refund show up within a few business days or should I follow up on this?
