This could be fixed in a newer version. A user of opendesktop (and thus KDE Store) reported the issue on our forums but doesn't have an account so I am reporting it on their behalf. https://forum.opendesktop.org/t/update-downloads-old-file/21075/3 is the report and includes screenshots of the issue and the metadata file on their PC.
