strange behavior in 17.1 when I upload document using a!fileUploadField()

When I upload a file using a!fileUploadField() and check the document ids of all other documents in that target folder, all doc ids get changed.
But when I upload a document through document tab in same folder then it doesn't change the doc IDs of other docs.
Am I doing something wrong or Is this a bug in 17.1?
Please help, thanks in advance.
