Zoho Bookings ePHI option unavailable

Zoho Bookings ePHI option unavailable

Hello!
While customizing my booking form in Zoho Bookings, it seems I am unable to delete preloaded fields and replace info like name, email, and contact number with fields that have the ePHI tag activated. I tried changing the field description, but it automatically changes itself back. It's worse for the Register Users form where I cannot change the preloaded name field at all. You can see the lack of delete option in the screenshot as I hover over the name field.

Can Zoho please allow the preloaded fields to be deleted?
