Double blind review

I am using Application Version - e.g., OJS 3.1.2. I sent a file to reviewers for double blind review. It doesn’t removes all the meta data as the orignal submission is sent with authors But the manuscript had authors name. I removed the names manually but can not find any options to upload it again as the file is on my desktop. The option asks to upload file from original submission or the review file.
Any help please.
