AFAIK, scanlation group usually have a folder (in the cloud) of works, start with RAWs, then the cleaner cleaned it, upload it in the same folder (with different names of course), then the typesetter insert the text, then QC will check the overall product, if there's anything that needs to be done, QC will give it to the one in duty which will then correct it and upload it (again to the same folder), which will QC'ed again until it's release ready
those last steps are sometimes causing the wrong files to be uploaded to sites (their own or mangadex)
