Can't change author metadata on image export [Exporting copyright with Metadata none]

How do I remove or at least change the author while exporting the image? I want to keep all camera info thoug. Since recently, something changed and my author/creator name changed to Adobe account name everywhere (EXIF, IPTC, XMP), but I don't use that name anywhere.. This doesn't make any sense in my case.  It's much better for me to just not use any name then...
