Ok,
I found the problem.

First, It seems that if you change the scraper setting via the Addons section it doesn't affect on the Library scraper settings, it just change the addon settings.
So in order to apply the wanted settings, this should be done via "Videos -> Files -> Change Content" window (see image below), there you need to enter to the scraper Settings and change it, and then run and apply the scraper on the TV Show.

The second issue is that "Certification Country" must be included in the Content Ratings results which returns for the specific Tv Show, if it doesn't there it shows it as empty.
For example if a TV show returns this:
"content_ratings":{"results":[{"iso_3166_1":"DE","rating":"16"},{"iso_3166_1":"GB","rating":"15"}]}
It means that you will get the value only if you select GB or DE as your "Certification Country" in the settings.

So it leads to my question/request: Is there any way to take a default Content Rating if the selected "Certification Country" isn't exist for a specific TV Show? (For example the first item in the Content Rating results)
Because for example as I posted above, some TV Shows has US content rating some of them has GB, so it means if I select US in "Certification Country" some of the TV Shows won't have this Content Rating value.

And by the way, what is "Certification Prefix" means?

Just FYI. The Python version of this scraper provides the US MPAA rating (if available) if there is no rating for the selected certification country.
