Some drawbacks to this feature are that you lose a little control when you are typing. Word formats for you and some users do not like this. Also, on certain items, you will get a number when you do not expect or need one. For example, you have an attorney whose name begins with an initial (A. George Smith). When you type the name and press ENTER, the first initial "A." converts to an automatic number.
Hi Enas, it sounds like the issue you are experiencing is about the PDF Export process. Have a look at this thread on the Adobe Community support forum: It seems to suggest that corrupt image files can cause problems like this. You also might want to check that you enough space on the disk you’re exporting the PDF too – if it runs out of room then you would get errors. Sorry I can’t help much more than give you some general ideas. Best of luck resolving the issue. Cheers Philippa
If you’re a self-taught InDesign user, you may not have been introduced to automatic page numbering, one of the biggest time-saving features in the program. InDesign allows you to set up the page numbering feature in your Master Pages. Then, as you add or shuffle pages, InDesign updates individual page numbers accordingly. You can style the page number any way you like.
Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
