What happened to the ‘Repay Balance’ button?

In the ‘Payments Dashboard’ section of Amazon Seller Central there is a grey button labelled ‘Repay Balance’ under ‘Funds Available’ that used to direct you to an area where you could make a transfer to Amazon of your choice.

Now when you click on the button, it just redirects you to a page showing previous payment periods. The field and buttons where you could input an amount to transfer are gone.

Anyone have any idea what happened to them and if there is a way to access the ‘Repay Balance’ area?
