- Scenario
- Merging PDF documents or adding new pages that contain active, duplicate form fields.
- Observed behavior
- When pages are added, fields with identical names share values or overwrite each other, causing radio buttons to lose their unique names and designated export values.
Before attempting to merge or edit your PDF files, save a separate copy of your original forms to prevent irreversible field renaming or accidental data overwriting.
Assign Unique Names to Independent Form Fields Before Merging
Prevent the PDF editor from linking or overwriting fields by ensuring every independent radio button group has a unique name before you combine the files.
According to standard PDF specifications, form fields that share the exact same name are treated as a single linked entity. If you merge pages containing identical field names, the application will automatically force them to share the same value.
Open the individual PDF document containing the original form fields before any merging has taken place.
Enter Form Editing mode, right-click the specific radio button, and select 'Properties' from the context menu.
Navigate to the 'General' tab and change the 'Name' text box to a completely unique identifier.
Repeat this renaming process for all independent fields, save your document, and then proceed to add the pages to your main PDF.
Create the Complete Document Layout Before Adding Fields
Avoid the complications of merging active forms entirely by combining your static base pages first, then adding the interactive form fields later.

Frequently Asked Questions
Why do PDF form fields automatically copy data from other fields?
According to standard PDF specifications, fields that share the exact same internal name are treated as a single entity. Typing into one field or changing its selected value will automatically update all other fields with that identical name across the entire document.
Can I merge two filled PDF forms without losing the entered data?
Merging filled forms can overwrite data if the fields share names. To safely merge them without losing the entered data, you should 'flatten' the PDF forms first. This converts the active, editable fields into static text before you combine the pages.
How do I change the export value of a radio button?
To change the export value, enter your PDF editor's form editing mode, right-click the radio button, and select Properties. Navigate to the 'Options' tab to modify the 'Radio Button Choice' or export value to your required data output.
