Avast Polish support helped me with this.
I made new installation of avast and avast backup on other device (tablet Samsung galaxy tab 7). In this device it was possible to pick archive device.
after this another try on Samsung note and there also was option to pick archived device.
Sorted. On the backup app go “browse backups” then choose “device” then it will show both “active” and “archived”.
Choose “archived” and then restore what you want.
