About the backup not showing! did you change the default location of backups during installation?
can you please check /opt/mikrowizard/server-conf.json to check the lines that specify the backup and firmware folder on your server? ( don’t send other lines as it may expose passwords and cipher key)

    "PYSRV_BACKUP_FOLDER":"/backups/",
    "PYSRV_FIRM_FOLDER":"/firms/",
