Range query against age_rating doesn't work as expected

[briandking]

Steps to reproduce

1. Tag a series with an age_rating of 5 in Komga
2. Search for age_rating:5 to verify it works
3. Search for age_rating:[40 TO 50] and the series with age_rating:5 will show up in the results

Expected behavior

Only comics with an age rating falling inside the numeric range should be shown.

Actual behavior

The series with an age rating of 5 shows up in a range search for [40 TO 50]
