After searching the web, I found that there are 2 type of bookmark in pdf.
first is normal bookmark, with "Set Destination" option when you right-click on the bookmark.
You create this by Ctrl+B.
second is tagged bookmark, without the "Set Destination" option.
You create this by merging multiple pdfs together.
Now the question is, is there a way to convert all tagged bookmark to normal bookmark??
I have tried to delete all tags after merging, but the bookmark still does not show the "Set Destination" option.
It seems that when you combine files using the built-in functionality of Acrobat, each file is saved in a separate "Structure Element", which is a logical unit within the PDF. For most intents and purposes this doesn't mean much to the end-user. However, the bookmarks that are created during this process also contain this information and therefore behave in a different way to those that are created with Ctrl+B or even with a script.
In fact, a script is not even capable of differentiating between the two types (it's the "SE" key in the Outline Item dictionary, for those interested).
However, a plugin or a tool using an external library is capable of seeing this, and even changing it.
Fortunately, what you want to do is simple, you just need to remove this key and the bookmark is reverted to the "normal" type. The other way around can be more complicated.
I have written a small app that can do this, and it will be available to download (for free) from my website soon.
