CBZ Metadata in KOReader

So I've been sideloading manga to my Kobo Forma in .cbz format. Through the KoboUtilities plugin I've managed to add metadata to those cbz files in calibre and now Nickel does show metadata properly, but inside KOReader all of it is missing, including covers (it just takes 1st page as a cover instead of the ones applied in Calibre). Is there a way to send my .cbz files to my kobo with metadata so that KOReader sees it too? Again, through the method mentioned everything displays properly in Nickel but not KOReader (or plato as I've checked)
