No keypad to input custom tip

in Hardware
I submitted a ticket asking this question but have seen no response in the past week. Thought I'd ask here.
On the customer facing display, when the choice for "Custom Tip" is chosen, no keypad appears on screen to input an amount. Am I just missing something? Is there a setting that needs to be changed?

Three months later, this is still a problem. It's already ridiculous that I had to buy extra hardware to be able to accept tips, and it turns out the system doesn't even work.
