SharePoint keeps checking the documents out despite the setting set to No

1. Verify that the check-out setting is still set to "No": Double-check that the check-out setting for the document library is still set to "No". It's possible that this setting was changed accidentally.

2. Check for other workflows or event receivers: It's possible that there is another workflow or event receiver running on the document library that is checking out the documents. Check if there are any other workflows running on the document library and if they have any actions that could check out the documents.

3. Check the SharePoint logs: Check the SharePoint logs to see if there are any errors or warnings related to the check-out process or the System Account. You can use the ULS Viewer tool to view the logs.

4. Check for custom code: If there is any custom code running on the SharePoint site or server, check if there are any methods or functions that could be checking out the documents.

5. Check with the SharePoint administrator: If you don't have access to the SharePoint logs or server, check with the SharePoint administrator to see if they are aware of any changes or issues that could be causing the documents to be checked out.
