Just so you understand, this is a user to user forum, not a line to Adobe Tech Support or the engineers.
You might get lucky here, but I think this question is outside the scope of knowledge that most of us have and you might do better to open an official support case.
Symbols, AFAICR have always caused this. InDesign has a real bullets and numbering feature.

Thanks for your support and suggestion.
Kindly let me know how do I Contact Adobe Tech Support .
Thanks for your suggestion.
Actually this was my client requirement.
Tech support will tell you exactly what I did. There is no problem here.
Find out from your client why they think there is.
Apparently someone moved a similar thread from the Acrobat forum back over here (note to the OP: please mention when you are double-posting in different forums) so we now have two threads withthe same name and subject. I'm going to lock this one, and if you have furhter comments, please continue in http://forums.adobe.com/message/4539395
