Field in form cannot be seen while building but shows up in preview.

I have a field that I did create but I cannot see it while editing the form but the field is there when I preview it but has a long name on the top of it. Are you able to just remove the field and I will re add it later. Or assist me in how I can find the field to delet it.

You can use Jotform's field manager app https://apps.jotform.com/app/field_manager.

I believe you are referring the field with a long title like in my sample screenshot below:

Try the field manager and see if that helps. Let us know how it goes.
