Scenario

Observed behavior

Before you start

Before making any structural changes to your PDF, save a backup copy of the original file to prevent accidental data loss or overwriting during troubleshooting.

Solution 1

Verify Page Range and Insertion Settings

Double-check the Add Pages dialog settings to ensure the correct file and page ranges are selected before confirming.

1
Open Insert Pages tool

Navigate to the Tools pane, expand the Pages menu, and select 'Insert from File'.

2
Select the correct source file

Browse to the file you want to insert and click Select. Ensure you haven't accidentally selected the current active document.

3
Configure the page range

In the Insert Pages dialog box, verify that the 'Page Range' correctly targets the pages you wish to add.

4
Confirm insertion location

Select whether to insert the pages 'Before' or 'After' a specific page number, then click OK.
