Repayment Slider has gone

I want to pay some of my transactions earlier, but the slider for the transactions has gone.

How do I repay individual transactions?

Oh, same for me just now, but it was definitely there earlier this morning.

This happened to be before and I was told by support that it was disabled while my direct debit was pending to avoid changing the payment amount, but this doesn’t seem right because I definitely replanned a transaction this morning, and now suddenly on the same day I can’t. My direct debit payment went out today.
