A field can be added to multiple form sections of the same form. Currently, it's rendered each time, the one that actually gets used when the form gets submitted might not be the one modified by a user. This leads to confusion when their changes to that field have no apparent effect upon saving a form. Having the same field showing on the same form in two different sections, the later one will not be writable.

1. Add the same field on 2 different places on a form, for example, one time on the header and one time on one of the tabs. It's easier to observe the issue with a checkbox field.
2. Select one of the checkboxes and save.
3. Refresh the form.
4. Observe that none of the checkboxes is selected.

Remove one of the fields from the form so that it appears one time only.
