Invoicing problem with WooCommerce Deposits

My client is reporting an issue where invoices are coming across without a “pay here” link. I don’t know if this is a recent issue or not, and I’m not even 100% certain that this is the right forum for this question. But all of my software is up-to-date, and yet this plugin isn’t doing what it’s supposed to.

Any suggestions or help would be most appreciated.
