Appointment field: Blank timeslot

On my templates Southwestern Hearing Centers Appointment Request and Southwestern Hearing Centers Appointment Request Form, the appointment section on both, I cannot see the times in the individual boxes.

I've researched like crazy and cannot get this fixed. Can someone tell me how to make the times visible please?

The issue might be related to the form theme you're using. I cloned the form link you provided and I didn't see the appointment field. 

Could you please share the correct form URL so we can check it further?

I believe you have injected CSS in your form due to which the time is not visible on the slots. The font color is currently white and the background is also white.

Please inject this CSS in your form:

.appointmentSlot {
    color: black!important;
}
