What Went Wrong?

The book filter UI is missing populated options for several fields that should offer selectable values. The affected filters currently do not populate their option lists, which makes those filters unusable or incomplete.

Affected filters:

• age rating
• content rating
• metadata match score
• published year
• file size

How Can We Reproduce This?

1. Open Grimmory.
2. Go to the book browser/library view.
3. Open the book filters UI.
4. Check the available options for:
   • age rating
   • content rating
   • metadata match score
   • published year
   • file size
5. Notice that these filters do not have populated option values.

What Should Have Happened?

Those filter categories should populate with the available option values derived from the current book/library dataset so users can filter on them normally.
