Parental Ratings are still not working for audiobooks

[justanotheruser 2]

Steps to reproduce:

1. Create an audio books library

2. Add any book to it with `.nfo` metadata. Despite metadata for this book contains `<mpaa></mpaa>`  it will be ignored and then removed from the file

3. Set parental rating one more time (this is a screen from the parental account)

4. Login to child's account, see that books were added to "Suggestions" screen :

5. But still are missing on the main "Audio Books" screen

 

6. I've tried everything, restarting the server, scanning the library, refreshing metadata, replace all metadata, deleting and creating library from scratch (it resulted in missing entire parental ratings that I've carefully set for 100+ books). Nothing is working. But as soon as I uncheck this checkbox all books appear on the child's account:

But in that case absolutely all books appear on the child's account without any actual parental rating filtering.

I see that similar bugs were reported several times already, but no actions were taking:

I've attached logs as well (debug log enabled), but I don't see any errors or other useful info there. Please, let me know if any other information can be provided. The parental rating is working without any issues for Movies and TV Series on the same server for the same parent's/child's account, only audio books are completely broken.
