remove placeholder from the phone number field

Hi, I'm looking at my form and the phone field is showing , (comma) as a place holder. I would like to remove that. It will be great if I could add the input mask i.e., (###) ###-#### as a placeholder instead. How can I achieve this?

However, the input mask appears when I click in that phone number field box, to enter the value.

Hello,

Thank you for your message.

In this case, the comma has a glitch in the field but now ha been fixed.

You can add a place holder under the Advance Properties:

Thank you. It is fixed now!
