While configuring "Restore from Manifest" job Ranger fails to add existing savepoint.
All files are present and reachable by Ranger.

One or both metadata files have some extra content that prevents Ranger from reading it in xml format.
In one particular case both files began with
;;x...<?xml version="1.0" encoding="utf-16"?>
basically random chars before opening tag.
Metadata files are xml files, so, they should strictly follow xml format.
Delete extra content from both files and try to add manifest in job config.
A correct manifest file should start with the opening line with nothing before this:
<?xml version="1.0" encoding="utf-16"?>
