Hey there @SVarnavi06. Thanks for the bug report. We'll be sure to update the file with the new changes and put them in the project. We haven't even considered that overwriting might not be desired behavior for a contact list. We'll be sure to address this and feature you in the small tips section and project details for the specific project.
Thanks for contributing.
