It appears your JotForm was on a different language when you have added the fields. Unfortunately, there is no automatic translation for this should you change your account's language settings to default English.
What you need to do is remove the said field and then add it again. However, by doing so, you will have to redesign the layout as the IDs and classes referenced from the old fields which was picked up by the CSS will be different. So you will have to go through the editing of the design again after the replacing of the old Paypal field.
If you have questions, please do let us know.
