Resolved bookmark saving issue, which causes the bug when we try to retrieve the saved bookmarks.

* Enhanced the `isBookMarkExist` method, addressing a bug that prevented the addition of new bookmarks for the same file. The method has been refactored for improved functionality.
* In the debug version, added informative logs to provide developers with insights into the bookmark-saving functionality.
