All posts containing watched words are automatically hidden — score_to_hide_post is 0.0

Thanks for the suggestion! I tried adjusting the Hide Post Sensitivity site setting in the admin panel, which has four options: Disabled, Low, Medium, and High.
However, I found that only Disabled works. No matter whether I choose Low, Medium, or High, the score_to_hide_post value remains 0.
Do you know why this happens?
