Problems Generating Forms in GUI View

Problems Generating Forms in GUI View

I am attempting to create my first application and am running into some issues. When I create a new field on a form or rearrange the order of my fields and save the changes, the rest of my fields get moved around or some get deleted orduplicated. For example, if my form includes the following fields:

First Name
Last Name
Email
Phone

...and I add an 'address' field and click 'done,' the form is refreshed and my fields change to the following fields:

First Name
First Name
Last Name
Last Name
Email
Address

...or something to that effect. It only displays this way in the GUI. When I click to view my application, all of the fields display correctly. Any idea what is going on? This is very annoying.
