@Sundraiz-Shah Thanks for the updates! After testing, I found the following issues:

1. No feedback for invalid input:
   • When entering text not in the list (for Licenses or Programming Languages), there’s no feedback.
   • For Keywords, entering a duplicate value should trigger a notification informing the user that the keyword already exists.
2. Layout and responsiveness issues:
   • When resizing or zooming the browser window, layout problems occur.
   • At higher zoom levels, some items and borders overlap or disappear. The bottom border is sometimes missing, and responsiveness is inconsistent across screen sizes.
3. JSON download issue:
   • The download function for the JSON file doesn’t work properly.
4. Invalid JSON output:
   • "null": "" entries are being added to the Contributor, Author, and Maintainer objects.
5. Missing delete confirmation:
   • There’s no confirmation prompt when deleting rows from the Copyright Holder table.
6. Email placeholder:
   • Please update the placeholder text for the Email field in the Persons tab.
7. Merging issue:
   • When merging multiple rows, roles are not merged correctly. For example, if Contributor, Author, and Maintainer are all selected for a person in different rows, only Contributor appears in the merged row.
8. Duplicate person validation in Persons tab:
   • When adding a new person, if another entry with the same Given Name and Family Name already exists, the new row should not be added. And a notification should appear to inform the user that the person already exists in the table.
9. Duplicate copyright holder validation:
   • When adding a new Copyright Holder, if a record with the same Legal Name already exists, a notification should be presented to user and prevent adding duplicate entries.
