Offline Apps - Problem with editing form

Good afternoon,
I'm building an application that must run Offline and for this I am using the Offline Apps module. The problem I'm having comes after recording the fields of a form and return to the editing of the same form fields that are Integer, Decimal or Date arise with the id of the form itself. Text fields, Combo Box and Check Box appear all with the alleged content. In the Database fields are the values that have been entered correctly. Any idea what could be happening? Basei me Offline Apps Sample and Inspections application.
