New Cancellation Process Problem

I had a new buyer buy two identical items.

One they paid for and the other remained on the awaiting shipment list.

Then we get a message from the buyer that says they made a mistake with the 2nd item could we please cancel it.

No worries I thought....

First time I've used this new process so I chose the option the buyer requested the cancellation OR there is a problem with the address.

Sent a message to the buyer letting them know they would have to agree.

Short time later I get a message from ebay saying the transaction has been cancelled and I don't need to do any more. So the buyer must have agreed I assume.

But... this item is still sitting on my awaiting payment list with the status showing as cancelled. The little red envelope symbol. Been like this for two days now.

 

What do I have to do to get this dumfounded process to complete cleanly and remove this item from my list?
