Unable to set end date for scheduled payments

Unable to set an end date for recurring scheduled payments.

Details to reproduce:
On the payments tab, selected “Make a bank transfer”.
Entered recipient details and selected “Next”.
Received a message about possible scam, since the name couldn’t be cross-checked with the account numbers – it’s definitely the correct details, though.
Now, when I flick the toggle to make it a recurring scheduled payment, and enter the payment amounts, the persistent “we couldn’t verify the details” message covers the options for setting the end date of the recurring scheduled payment.
