Payment Information Amount does not show

On the registration form for all my events, the Payment Information (the price they will be paying) does not show up. The field is blank. It seems to be on every browser for every event so it doesn't seem like a CSS formatting issue. This is the case on all amounts whether it's the base amount, discounted amount, or gross amount. The correct price does get forwarded to PayPal, but just does not show up on the registration form. This just started a few days ago after it had been working fine for months.
