Contributed Fragment Collection's content is not correct after deployment

Issue

• We have created a Contributed Fragment Collection, carefully following the documentation
• The collection contains two fragments
• After successful deployment, we see only one fragment is present twice in the portal

Environment

• Liferay DXP 7.2+

Resolution

• The fragment.json files are missing the "fragmentEntryKey" : "[value]" for both fragments
• Add those values to all of your fragments' JSON files in your collection and redeploy to make it work properly

Additional Information

• The documentation of Developing A Fragment Using Desktop Tools will be updated with that information by LRDOCS-8206
