Is there a glitch with refund? cannot cancel transaction after refund?

Since yesterday, when I refund my customers, the transaction is still showing as paid, with the "$" sign still in solid blue.

Normally when we refund a transaction, the solid blue dollar sign will turn into a translucent dollar sign with a diagonal line on it, indicating that a refund has been issued, and from there on, I will be able to cancel the transaction and get my final value fee back.

 

But ever since yesterday, this is not working. I have refunded my customer, but I cannot cancel the transaction.

 

Anyone having the same issue?

 

How do we resolve this?
