Why is the notification email for submissions and confirmation email fields limited?

Hi Good day,

I would really appreciate your quick response on this. I can not find the other fields when I am editing the notification format, the fields are somehow limited or cut off (Not showing the whole form). I am trying to put titles between fields for the submission emails and confirmation emails to be more cleaner but I could not find the other fields on Jotforms>Settings>Emails>Notifications>Edit. Kindly let me know how to show all the fields while editing the notification format. Thank you.

The number of characters in your email notification should be fine, please delete the old notification and create a new so all new fields will reflect on the new nofitication.
